Question

When Elyse moved last weekend, the circular glass top for an end table broke. To replace it, she bought a circular glass top with a diameter of 20 inches.

What is the approximate area of the circular glass top Elyse bought?

Answer 1

A = 314 inches^2

Explanation:

We know the diameter of the glass. We need to find the radius

d = 2r

20 = 2r

Divide each side by 2

20/2 = 2r/2

10 =r

To find the area of the glass

A = pi r^2

A = pi * 10^2

A = pi*100

A = 100 *(3.14)

= 314 in^2
