Question

What is the area of a circle whose radius is 20 meters?

Answer 1

What is the formula for the area of a circle?

Answer 2

The area of the circle = Pi x (r^2)
Where Pi = 3.14 and r = radius.
In this problem, we have Radius(r) = 20 meters
=> Area of the circle = Pi x (20^2)
= 3.14 x 400
= ???

Answer 3

\[20\pi m ^{2};40\pi m ^{2};200\pi m ^{2};400\pi m ^{2}\]
