Question

The base of a shipping drum is in the shape of a circle with a diameter of 24 inches. Which of the following is closest to the circumference of the base of the shipping drum? (Use 3.14 for .)

A.
75.36 inches
B.
1,808.64 inches
C.
37.68 inches
D.
452.16 inches

Answer 1

Explanation:

Circumference of a circle is calculated by
`\boxed{2 \pi r}` where r is the radius of the circle. In the question, diameter is given which is double the length of radius. It means, r = 24 / 2 = 12 inches.

Now put the values into the formula,

= 2 × 3.14 × 12 inches

= 37.68 inches.

`\therefore` Circumference of the base of the shipping drum is 37.68 inches (c)
