Question

A hose is coiled into circular loops about 30 inches in diameter. the length of each loop is about...

a. 7 ft
b. 8 ft
c .9ft
D. 10ft​

Answer 1

b. 8 ft

Explanation:

We use the formula for the circumference of a circle to find the length of each loop.

Circumference of a circle = 2πr or Dπ

Where: π = pi

r = radius of the circular loops

D = Diameter

π =
`(22)/(7)`

D = 30 inches

Use Circumference of a circle = Dπ

Circumference of a circle = 30 x (22/7)

= 30 x 3.142857143

= 94.28571429 inches

Convert 94.28571429 inches to feet (ft)

12 inches = 1 ft

94.28571429 inches = 94.28571429/12

= 7.857142858 ft

≈ 8 ff
