Which of the following is the closest to 25?
a. Perimeter of a square with side length
b. Diameter of a circle with radius
c. Perimeter of an equilateral triangle with side length
Both and
Both and
Find the values of a, b, and c.
Since is closest to , the answer is c.
Example Question #31 : How To Make Geometric Comparisons
Find the correct relationship between the perimeters of these shapes.
a. A rhombus of side length 4
b. A regular hexagon of side length 2
c. A regular pentagon of side length 3
Find the perimeters of the shapes.
A rhombus has four identical sides:
A hexagon has six:
A pentagon has five:
The correct relationship is .
Example Question #33 : How To Make Geometric Comparisons
, , and each refer to the fractions of their respective figures that are gray.
Which statement is correct?
Examine the diagram below, which shows all three figures with additional lines.
is represented by four colored portions out of eight, so .
is represented by six colored portions out of twelve, so
is represented by four colored portions out of six, so .
. Since
and
,
it follows that .
Example Question #34 : How To Make Geometric Comparisons
Figures NOT drawn to scale
Let , , and refer to the diameters of their respective circles.
Which is a true statement?
Circle has radius 4; its diameter is twice this, which is 8.
Circle has area . Since the area is equal to times the square of the radius, that is,
,
substitute for the area and solve for :
The diameter of the circle is twice this, or 4.
Circle has circumference ; its diameter is the circumference divided by , which is
Therefore, .
Example Question #32 : How To Make Geometric Comparisons
Note: Figures NOT drawn to scale.
In the above diagram, let , , and represent the radii of their respective circles.
Which is a correct statement?
The radius of a circle is one half its diameter. Circle A has diameter 16, so its radius is half this, or 8.
The relationship between the area of a circle and its radius is given by the equation
Circle B has area , so substitute this for the area:
,
the radius of circle B.
The radius of a circle is its circumference divided by . Circle C has circumference , so divide this by :
and , so .
Example Question #33 : How To Make Geometric Comparisons
, , and each refer to the fractions of their respective figures that are gray.
Which statement is correct?
Examine the diagram below, which shows all three figures with additional lines.
Note that each square has been divided into eight congruent parts. , , and are represented by 3, 4, and 5 colored portions, respectively, so
,
and .
Of the four choices, only is correct.
Example Question #31 : How To Make Geometric Comparisons
Examine the above three figures. All three squares have the same area.
Of Figure B and Figure C, which figure(s) have the same area shaded in as does Figure A?
B but not C
Both B and C
C but not B
Neither B nor C
C but not B
Figure A is divided into twelve regions of equal area; six are shaded in, which make up of the area. Reduce this to lowest terms by dividing both halves by greatest common factor 6:
.
Figure B is divided into sixteen regions of equal area; seven are shaded in, which make up of the area. This is in lowest terms, since 7 and 12 are relatively prime. , so Figure B does not have the same shaded area as Figure A.
Figure C is divided into eight regions of equal area; four are shaded in, which make up of the area. Reduce this to lowest terms by dividing both halves by greatest common factor 4:
.
Figure C has the same shaded area as Figure A.
The correct response is "Figure C, but not Figure B."
Example Question #38 : How To Make Geometric Comparisons
Examine the above three figures. All three squares have the same area.
Of Figure B and Figure C, which figure(s) have the same area shaded in as does Figure A?
Figure C but not Figure B
Neither Figure B nor Figure C
Figure B but not figure C
Both Figure B and Figure C
Both Figure B and Figure C
Figure A is divided into twelve regions of equal area; nine are shaded in, which make up of the area. Reduce this to lowest terms by dividing both halves by greatest common factor 3:
.
Figure B is divided into sixteen regions of equal area; twelve are shaded in, which make up of the area. Reduce this to lowest terms by dividing both halves by greatest common factor 4:
Figure B has the same shaded area as Figure A.
Figure C is divided into eight regions of equal area; six are shaded in, which make up of the area. Reduce this to lowest terms by dividing both halves by greatest common factor 4:
.
Figure C has the same shaded area as Figure A.
The correct response is "Both Figure B and Figure C."
Example Question #39 : How To Make Geometric Comparisons
Refer to the above diagram. Let , , and stand for the fraction of their respective squares that are shaded in. Which is correct?
Below are the same figures, but with some additional lines drawn so that each square is divided into equal parts.
is represented by 6 parts out of 12, so .
is represented by 4 parts out of 9, so .
is represented by 3 parts out of 8, so .
These fractions can be compared by expressing them in terms of a least common denominator - :
Comparing numerators, we see that .
