Answer:
The formula for area of a circle is : A = PI x r^2
A) find the are of the two circles, subtract the two to find the area of the side walk:
Outside circle: A = PI x 10^2
Area = 100PI
Inner circle: A = PI x 8^2
Area = 64PI
Area of sidewalk:
100PI - 64 PI = 36PI
B) replace PI with 3.14:
Area = 36 x 3.14 = 113.04 square meters.
