Example Question #221 : Geometry
A sphere has diameter 12. What is 75% of its volume?
The radius of a sphere is half its diameter, which here is 12, so the radius is 6. The volume of the sphere can be calculated by setting in the formula:
75% of this is
Example Question #222 : Geometry
Find the volume of a rectangular prism with the following information:
The formula for volume of a rectangular prism is,
.
For this problem, since
the solution would be
.
Example Question #223 : Geometry
What is the measure of a right angle?
The measure of a right angle is degrees.
Example Question #224 : Geometry
Figure NOT drawn to scale.
If and , evaluate .
More information is needed to solve the problem.
The measure of an exterior angle of a triangle is the sum of the measures of its remote interior angles, so
Example Question #771 : Ssat Upper Level Quantitative (Math)
Figure NOT drawn to scale.
If and , evaluate .
The measure of an exterior angle of a triangle is the sum of the measures of its remote interior angles, so
Example Question #772 : Ssat Upper Level Quantitative (Math)
If the vertex angle of an isoceles triangle is , what is the value of one of its base angles?
In an isosceles triangle, the base angles are the same. Also, the three angles of a triangle add up to .
So, subtract the vertex angle from . You get .
Because there are two base angles you divide by , and you get .
Example Question #3 : How To Find An Angle In An Acute / Obtuse Triangle
Note: Figure NOT drawn to scale.
Refer to the above diagram.
Which of the following could be a measure of ?
All of the other choices give a possible measure of .
The measure of an exterior angle of a triangle is the sum of the measures of its remote interior angles, so
.
We also have the following constraints:
Then, by the addition property of inequalities,
Therefore, the measure of must fall in that range. Of the given choices, only falls in that range.
Example Question #773 : Ssat Upper Level Quantitative (Math)
Refer to the above diagram.
Which of the following could be a measure of ?
All of the other responses are correct.
All of the other responses are correct.
The measure of an exterior angle of a triangle is the sum of the measures of its remote interior angles, so
or
Therefore, the maximum value of is the least possible value of subtracted from the greatest possible value of :
The minimum value of is the greatest possible value of subtracted from the least possible value of :
Therefore,
Since all of the choices fall in this range, all are possible measures of .
Example Question #225 : Geometry
One angle of a right triangle has measure . Give the measures of the other two angles.
This triangle cannot exist.
This triangle cannot exist.
A right triangle must have one right angle and two acute angles; this means that no angle of a right triangle can be obtuse. But since , it is obtuse. This makes it impossible for a right triangle to have a angle.
Example Question #226 : Geometry
One angle of a right triangle has measure . Give the measures of the other two angles.
This triangle cannot exist.
One of the angles of a right triangle is by definition a right, or , angle, so this is the measure of one of the missing angles. Since the measures of the angles of a triangle total , if we let the measure of the third angle be , then:
The other two angles measure .
