Question

a hamster wheel has a 7 inch diameter. How many feet will a hamster travel in 100 revolutions of the wheel?

Answer 1

1 revolution = pi * diameter
= 3.14 * 7 inch
100 revolution
= 100 * 3.14 * 7 = 2198 inches
= 2198 / 12
= 183.17 feet

Answer 2

The hamster wheel of 7 inch diameter will travel 183.17 feet in 100 revolutions of the wheel.

For the hamster wheel of 7 inch in diameter, we need to find how many feet a hamster travels in 100 revolutions of the wheel.

What is the circumference of the circle?

The circumference of the circle is the measure of the arc length.

circumference of the circle = 2$\pi$r

Where r is the radius of the circle

So, the circumference of the circle = 2$\pi$r

                                                        = 2 × 3.14 × 7/2 inch

                                                        = 21.98 inch

1 revolution = circumference of the circle

100 revolution = 100 × 21.98 inch

                        = 2198 inches

                        = 2198 / 12

                        = 183.17 feet

Therefore, a hamster wheel of 7 inch diameter will travel 183.17 feet in 100 revolutions of the wheel.
