Question

Find the circumference of a circle with diameter,

d
= 3.2m.
Give your answer rounded to 2 DP.

Answer 1

circumference=10.05 m

Explanation:

radius =diameter/2

=3.2/2

=1.6 m

circumference=2πr

=2*3.14*1.6

=10.048 m

=10.05 m

Answer 2

`circumference = \pi \: d \\ = 3.14 * 3.2 \\ = 10.05 \: m`
