Answer 1

23.55

Explanation:

Answer 2

23.55

Explanation:

We know it's three quarters of a circle since the angle is
`270`°

Therefore we can calculate like a normal circle and multiply by
`(3)/(4)`.

The formula for calculating the circumference is 2 times pi times the radius or
`2\pi r` .

`\pi=3.14\\2*\pi=6.28\\6.28*5=31.4\\31.4*(3)/(4)=23.55`
