Question

work out the circumfrance of this cirlce take pi to be 3.142 and write down all the digits given by your calculator raduis 10cm

Answer 1

`C=68.4`

Explanation:

`Circumference=2\pi r`

Pi = 3.142

r (radius) = 10 cm

`C=2(3.142)(10)`

`C=(6.84)(10)`

`C=68.4`

Therefore, circumference of a circle with 10 cm radius is 68.4.
