3. How many inches of tape would you need to go once around the middle of a ball that has a diameter of 7 inches?
1a C=2xPIxR = 7 times PI = 21.98
1b C = 12xPI = 37.68
2a A = PIxRxR = 12.25 x PI = 38.48451
2b A = PIx6x6 = 36 x PI = 113.097
3 C = 7 x PI = 21.99
PI = 3.14159, 3.14 used in some answers
