Question

A circular garden with a radius of 8 feet is surrounded by a circular path with a width of 3 feet.

What is the approximate area of the path alone? Use 3.14 for Pi.

172.70 ft2
178.98 ft2
200.96 ft2
379.94 ft2

Answer 1

B. 178.98 ft2

Explanation:

Answer 2

178.98 ft2

Explanation:

we know that

The area of the circular path alone is equal to subtract the area of the circular garden from the area of the complete circle (circular garden plus circular path)

so

`A=\pi (r_2^2-r_1^2)`

where

`r_1=8\ ft` ---> radius of circular garden

`r_2=8+3=11\ ft` ----> radius of the circular garden plus radius circular path

substitute

`A=3.14 (11^2-8^2)=178.98\ ft^2`
