Question

Find the area of a circle with a diameter of 8 inches. Use 3.14 for π.

Answer 1

(8÷2)×(8÷2)×(22÷7) = 50.29 square inches

Answer 2

50.24 square inches

Explanation:

Use the formula
`A = \pi r^(2)`

Find the radius, r, by dividing the diameter by 2.

8/2 = 4

Now plug the numbers into the formula.

`A = \ 3.14 (4^(2) )`

`A = 3.14(16)\\A = 50.24`
