Answer:
23.55
Step-by-step explanation:
We know it's three quarters of a circle since the angle is [tex]270[/tex]°
Therefore we can calculate like a normal circle and multiply by [tex]\frac{3}{4}[/tex].
The formula for calculating the circumference is 2 times pi times the radius or [tex]2\pi r[/tex] .
[tex]\pi=3.14\\2\times\pi=6.28\\6.28\times5=31.4\\31.4\times\frac{3}{4}=23.55[/tex]
