Question

Find the circumference of the circle. Use 3.14 for the value of ", Round your answer to the nearest tenth.

Answer 1

The formula for circumference is 2*pi*r
We plug in these values and get 2*pi*2.9
Or 18.2 in

Answer 2

18.2 cm

Explanation:

Given,

Radius of the circle = 2.9 in.

Therefore,

Circumference of the circle

`= 2\pi r`

`= 2 * 3.14 * 2.9 \: cm`

= 18.212 cm

As,

It has asked for nearest tenth so it will be,

18.212 cm

Since, there is 1 in the hundredth digit so it will round to 0.

Hence,

18.2 cm is the required circumference of the circle rounded to nearest tenth. (Ans)
