The area of a trampoline is 49 pi sqared. What's the diameter of the trampoline?

The diameter is 14

Step-by-step explanation:

The area of a circle is given by

A = pi r^2

We know the area is 49 pi

49 pi = pi r^2

Divide each side by pi

49 pi / pi = pi r^2/pi

49 = r^2

Take the square root of each side

sqrt (49) = sqrt (r^2)

7 = r

We want the diameter

d = 2r

d = 2*7

d = 14
