Step-by-step explanation: So you are finding the perimeter of the circle. You have a radius of 15, the perimeter for a circle is C=2pir. Now we can do C=2pi(15). The answer is 30pi or C=2 x 3.14 x 15= 94.2 Hope this helps.
50-9.75-1.25-1.25=37.75. 1/5 of 50 is 10, so I subtracted 27.75 from 37.75 and got 10.00. The 27.75 made the difference 10.00, so that´s how I got the answer.
