Question

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

Answer 1

Answer:

B. 178.98 ft2

Step-by-step explanation:

Answer 2

Answer:

178.98 ft2

Step-by-step 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

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