A wheelbarrow has a wheel with a diameter of 10 inches. What is the distance, in inches, that the wheelbarrow moves after 16 full rotations of the wheel? Use 3.14 for m.

Step-by-step explanation:

Using the formula for finding the circumference of a circle.

C = 2πr

r is the radius

radius = diameter/2

radius = 10/2

radius = 5in

C ,= 2(3.14)(5)

C = 20(3.14)

C = 31.4×2

C = 62.8in (for 1 rotation)

For 16 rotations;

C = 16×62.8

C = 1004.8in

The distance covered is 1004.8in

4.8 hours

Step-by-step explanation:

There are five guard that need to split 24 hours equally. To find the number we need to divide 24 by 5. That means each guard has to be on duty for 4.8 hours.
