Answer: 2/3 yard
Step-by-step explanation: First, Kevin cut a plank a yard long. That means that he has a plank thats a yard long. Next, he painted 1/3 of the plank black. Before, 3/3 (basically equals to 1 yard long) of the plank was unpainted. So, the equation will be 3/3 - 1/3 which is equal to 2/3 yard.
First, I would find the radius for both discs. To do so, divide the circumference by 2.
So.. 27.3/2=13.65. 22.5/2=11.25.
Afterwards, take the radius and use the formula: 2(3.14)r.
2*3.14*13.65＝85.722 and 2*3.14*11.25＝70.65.
Then, you subtract 85.722 from 70.65 which equals 15.072 which rounds to 15.
52, because 52 is a multiple of 13 (13*4 = 52)
22 x 4 = 88 feet(c) or 650 X 2 = 1300
