Question

The radius of the wheel of a bicycle is 14 inches.What is the distance,in feet,that the bicycle covers after ten full rotations of the wheels?

Answer 1

The circumference of a circle is C=2*pi*r
So for the tire C=2*pi*14 or 28pi
So 10 rotation would be 10 times the circumferece
28pi*10=280pi or 879.65ft

Answer 2

Since there are ten full rotations, the total distance covered is 880 inches

Circumference of a circle

The formula for calculating the circumference of a circle is expressed as;

C = 2πr

where;

r is the radius = 14inches

Substitute into the formula

C = 2(22/7)*14
C = 2 * 44
C = 88 inches

Since there are ten full rotations, the total distance covered is 880 inches
