66.666666 repeated decimal You would keep the 66 as is, and divide 2 by 3. That equals 0.66666666666 repeated, so the answer would be 66.666666 (rounded: 66.67)
SA: 2pi (r^2)+2pi(r)(h) In order to find radius (r) of the base you must divide 10 by pi then find the square root of the result √(10/pi)=r: 1.784cm h: a) 8.0cm b) 6.5cm c) 9.4cm 2pi (3.183)+2pi(1.784)(8)=109.673cm^2 2pi (3.183)+2pi(1.784)(6.5)=92.859cm^2 2pi (3.183)+2pi(1.784)(9.4)=125.366cm^2
