The circumference of the circle is approximately 94.64 centimeters. The shaded regions is 2/10 of the whole circle. What is the area of the shaded region. Round to the nearest hundredth.

Answer 1

Circumference = pi * diameter

94.64 = pi * diameter

diameter = 94.64/pi = 30.1127

radius = 15.0563

2/10 = 1/5 , so 1/5 * area = 1/5 * pi * radius^2 = (1/5)*pi * 15.0563=9.464
