Question

Lucien is standing on the circle in the center of a soccer field during a game. He is 10 yd from the center of the circle. Enter your answers in the boxes. What is the distance around the circle in terms of π ? yd What is the distance around the circle using 3.14 for π ? Round your answer to the nearest tenth if needed. yd

Answer 1

• 20π yd
• 62.8 yd

Explanation:

The circumference of a circle is given by the formula ...

C = 2πr

For a circle of radius 10 yd, the circumference is ...

C = 2π(10 yd) = 20π yd

Using 3.14 for π, the circumference is ...

C = 20(3.14) yd = 62.8 yd
