Question

A circle has a radius of 6.87 ft. What is the circumference of this circle? Use 3.14 for pi. Round your final answer to the nearest tenth. Enter your answer as a decimal in the box. ft

Answer 1

Answer: Circumference of circle is 43.1 ft.

Step-by-step explanation:

Since we have given that

Radius of a circle = 6.87 ft

We need to find the circumference of circle :

As we know the formula for "Circumference of circle ":

$C=2\pi r\\\\C=2\times 3.14\times 6.87\\\\C=43.1436\ ft\\\\C=43.1\ ft.$

Hence, circumference of circle is 43.1 ft.

Answer 2

C = 2pi r
C = 2 x 3.14 x 6.87
C = 43.1 ft

answer: 43.1 ft
