Question

The circumference of a wheel is 320.28 centimeters.

a) Determine the radius of the wheel.

b) Determine the area of the wheel.

Answer 1

radius is 50.95

area is 8158.55

Explanation:

cirumference = 2pi×r

or,320.28=2×(22/7)×r

or, r=320.28/(2×(22/7))

r=50.95 cm

area=(22/7)r^2

=8158.55
