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

Answer:

Factors are numbers you can multiply to get each number. For example, for 30 you would have factors of 1, 2, 3, 5, 6, 10, 15, and 30.  I got that because 1 x 30 = 30, 2 x 15=30, 3 x 10 = 30, and 5 x 6= 30.  If the factors are just 1 and that number it is prime.  If there are other factors, it is composite.  30 would be composite.
