Question

The circumference of a circle is approximately 131.88 centimeters What is the area of the shaded region (6/10 of a circle)

Answer 1

82.97cm^2

Explanation:

Given data

Circumference= 131.88 centimeters

We want to find the area of 6/10 part of a circle

Firstly, let us find the area of the circle

We need to get the radius

C= 2πr

131.88= 2*3.142*r

131.88=6.284r

r= 131.88/6.284

r=20.98 cm

Area= πr^2

Area= 3.142*20.98^2

Area= 3.142*440.16

Area= 1382.98cm^2

Hence 6/10 of a 1382.98

=0.06*1382.98

=82.97cm^2
