Question

The diameter of a circle is 24 feet. Using the formula A = r2, what is the area of the circle? Use 3.14 for pi. ft2 Circle with diameter labeled 24 feet

Answer 1

We know, Area = πr²
Here, r = diameter / 2
r = 24/2 = 12

Substitute the values, 
A = 3.14 * (12)²
A = 3.14 * 144
A = 452.16

In short, Your Answer would be 452.16 Ft²

Hope this helps!
