Question

What is the area of a circle whose radius is 4 ft?

4π ft²

8π ft²

16π ft²

64π ft²

Answer 1

It would be 50.24 ft
BTW in this case I used 3.14 for pi

Answer 2

The answer is 16π ft²

Explanation:

What he need to do is "act" like there is a triangle in the circle, so the radius is 4, 4*2=diameter, 8, thats the length of the triangle, the height of the triangle is 4, now we find the area of the triangle, 8*4=32, 32/2=16

This is for anyone who needs it in the future
