Two circles of a radius of  each sit inside a square with a side length of .  If the circles do not overlap, what is the area outside of the circles, but within the square?

Possible Answers:

Correct answer:

Explanation:

The area of a square = \dpi{100} \small side^{2}

The area of a circle is \dpi{100} \small \pi r^{2}

Area  = Area of Square \dpi{100} \small - 2(Area of Circle) =

Example Question #192 : Geometry

A parallelogram with right angles has side lengths of and . What is its area?

Possible Answers:

Cannot be determined

Correct answer:

Explanation:

Remember that a parallelogram with right angles is a rectangle. With that in mind, all you need to do is multiply those side lengths together, knowing that they are the length and width of a rectangle:

Example Question #193 : Geometry

Find the area of a rectangle given width 6 and length 9.

Possible Answers:

Correct answer:

Explanation:

To solve, simply multiply the width by the length. Using the formula, you get the answer as follows:

Additionally, you can alternatively solve this problem by drawing out a rectangle, creating 6 horizontal lines and 9 vertical ones, and then adding up the squares to reach your answer.

Example Question #12 : How To Find The Area Of A Rectangle

Three of the vertices of a rectangle on the coordinate plane are located at the origin, , and . Give the area of the rectangle.

Possible Answers:

Correct answer:

Explanation:

The rectangle in question is below:

Rectangle 3

The lengths of the rectangle is 10, the distance from the origin to ; its width is 7, the distance from the origin to . The area of a rectangle is equal to the product of its length and its width, so multiply:

Example Question #1 : How To Find The Length Of The Diagonal Of A Rectangle

What is the length of the diagonal of a rectangle that is 3 feet long and 4 feet wide?

Possible Answers:

4\ feet

7\ feet

6\ feet

8\ feet

5\ feet

Correct answer:

5\ feet

Explanation:

The diagonal of the rectangle is equivalent to finding the length of the hypotenuse of a right triangle with sides 3 and 4. Using the Pythagorean Theorem:

3^{2}+4^{2} = hypotenuse^{2}

25 = hypotenuse^{2}

hypotenuse = 5

Therefore the diagonal of the rectangle is 5 feet.
