Question

What is the area of this circle with an diameter of 6m? Express you answer using pie.

A = 3 pie m2
A = 6 pie m2
A = 9 pie m2
A = 36 pie m2

Answer 1

Hi there! The third answer is correct.

We can find the area of a circle by using the following formula:
Area = pi * (radius)^2
A = πr²

A circle with a diameter of 6 meters has a radius of 3 meters, since the radius is half of the diameter. Now we can fill in the formula and determine the area of the circle.

A = π * 3² = 9π m²
The third answer is correct.
Hope this helps you!
