Question

The diameter of a circle is 8 yards. What is tue circle’s area?
Use 3.14 for pie

Answer 1

50.24

Explanation:

The formula is A=pi x r^(2)

If we know that the radius is half of the diameter then we can half the diameter by 2 giving us 4 as our radius.

Now we add it into our equation

A=3.14 x 4^(2)= 50.27

Answer 2

16 yards square

Explanation:

Area of circle=radius square

To find the radius we divide the diameter by two.

Therefore 8÷2=4

4×4=16 yards

I hope this helps you in any way:)
