Question

The diameter of a circle measures 10 yd. What is the circumference of the circle?
Use 3.14 for π, and do not round your answer. Be sure to include the correct unit in your answer.

Answer 1

Answer:

31.4 yards

Step-by-step explanation:

Radius (R) = d / 2

R = 10 / 2 = 5 yards

Circumference (C) = 2 π r

C = 2 * 3.14 * 5 yards

C = 31.4 yards

Answer 2

The circumference of the circle is 31.4 yd.

From the question,

We are to determine the circumference of a circle whose diameter is 10 yd.

The formula for calculating the circumference of a circle in terms of diameter is given as

C = πd

Where C is the circumference

and d is the diameter

From the given information

d = 10 yd

and π = 3.14

Putting the parameters into the formula

We get,

C = 3.14 × 10

∴ C = 31.4 yd

Hence, the circumference of the circle is 31.4 yd.
