Please help what is number 5 i have done the rest!!!

Answer 1

Answer:

(4²πx2) + (8π x 4) = 201.061... OR 64π

Answer 2

Answer:

Step-by-step explanation:

5) r = 8/2 = 4 cm

Top and bottom = 2*πr²

                           = 2 * 3.14 * 4 * 4

                          = 100.48 cm²

Middle part = h * πd

                  = 4 * 3.14 * 8

                 = 75.36 cm²

Total = 100.38 + 75.36   = 175 .84 cm²
