Answer:

23.55

Step-by-step 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 $\frac{3}{4}$ .

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

$\pi=3.14\\2\times\pi=6.28\\6.28\times5=31.4\\31.4\times\frac{3}{4}=23.55$

100%/x%=20/15
(100/X)*x=20/15*x --I multiply both sides of the equation by X
100=1.33333333333*x --I divided both sides of the equation by .........................................(1.33333333333) to get X
100/1.33333333333=x
75=x
x=75
