Question

Find the circumference of the circle.

Answer 1

Answer:

• The circumference of the circle in term of pi = 10π inches

• The circumference of the circle us 3.14 as pi = 31.4 inches

Step-by-step explanation:

Given

The radius of the circle = r = 5 in

We know that diameter is twice the radius.

so d = 2r = 2(5) = 10 in

Finding the circumference of the circle in terms of pi

Using the formula to find the circumference of the circle

C = dπ

C = 10×π

C = 10π inches

Thus, the circumference of the circle in term of pi = 10π inches

Finding the circumference of the circle using π = 3.14

We know that the formula to find the circumference of the circle

C = dπ

Given

π = 3.14

substituting π = 3.14 to find the circumference of the circle

C = 10×3.14

C = 31.4 inches

Thus, the circumference of the circle = 31.4 inches
