Question

A circular game spinner with a diameter of 5 inch is divided into 8 sectors of equal area what is the approximate area of each sector of the spinner

Answer 1

2.45 in^2

Explanation:

So first, we need to find the area of circle.

A = π(r)^2 is the formula

The radius is 1/2 the diameter, so 5/2 = 2.5 in. Plug that bad boy in:

A = π(2.5)^2

(2.5)^2 = 6.25 in

A = π x 6.25 = 19.63 in^2 (Rounded to the hundredths place)

Now since we have 8 equal pieces, divide the total area by 8.

19.63/8 = 2.45 in^2
