Question

what is the difference in the areas of a circle with radius 14 ft and a circle with radius 10ft? round your answer to the nearest square meter

Answer 1

Circle area = PI * radius^2
10 foot circle = PI * 100 = 314.159265

14 foot circle = PI * 14^2 = PI * 196 = 615.7521601036

615.7521601036 -314.159265 = 301.5928951036

answer is C

Answer 2

C) 302 ft².

Explanation:

Given : A circle with radius 14 ft and a circle with radius 10ft.

To find : what is the difference in the areas.

Solution : We have given that radius 14 ft and a circle with radius 10ft.

Area of circle = π
`(radius)^(2)`

Area of circle 1 = π
`(14)^(2)`

Area of circle 1 = 196 * 3.14.

Area of circle 1 = 615.44 ft².

Area of second 2 = π
`(10)^(2)`

Area of circle 2 = 100 *3.14.

Area of circle 2 = 314 ft²

Difference = 615.44 - 314

Difference = 301.44 ft²

Rounded 302 ft²

Therefore, C) 302 ft².
