Question

A circle has a diameter of 36 cm. Which expression could represent the area of this circle in square cm?

Answer 1

3.14(18^2) basically do that

Answer 2

Explanation:

You haven't given the choices but I believe the equation below could represent the area of the circle:

(pi ~ 3.14) * (18)^2

The area for a circle is pi * radius squared, so to find the radius divide the diameter by 2.
