Question

Find the circumference of a circle with radius,

r = 1.7m.
Give your answer rounded to 1 DP.

Answer 1

About 10.7m.

Explanation:

Formula for Circumference:
`C=2\pi r`

We are given the radius of 1.7m.

Using 3.14 for pi:

`C=2*3.14*1.7\\\\C=6.28*1.7\\\\\boxed{C=10.676}`

10.676 ≈ 10.7

The circumference of the circle should be about 10.7m.

Answer 2

10.7 m

Explanation:

C = 2(pi)r = 2 * 3.14159 * 1.7 m

C = 10.7 m
