Question

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

Answer 1

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

Answer 2

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
