If you notice, the quarter circle has a radius of 10 feet. So you can find the circumference/perimeter by using the formula as normal (2pi*radius) to get 20*pi (2*pi*10 = 20*pi). Divide this by four (since it is a quarter circle) to get 5*pi.
You also notice that if you combine the two semicircles, you get a full circle, which means you can find the perimeter normally (which is 10*pi) 10pi+5pi = 15pi which is approximately 47.1

Step-by-step explanation:
Lay out the two fractions into a problem and then switch 6/15 into 15/6 after that, multiply 4/7 and 6/15, simplify the numbers. Your answer should be 30/21 as a improper fraction. Turn it into a mixed number and it should be 1 3/7
