Answer:

Explanation:

2) r = 16/2 = 8 cm

Area of top and bottom = 2*πr²

= 2 * 3.14 * 8 * 8

= 401.92 cm²

Midlle part = h * πd

= 6 * 3.14 * 16

= 301.44 cm²

Total = 401.92 + 301.44

= 703.36 cm²

3) Area of front and back =
2* (1)/(2)*b * h\\


= 2*(1)/(2) * 3 * 4\\\\= 12 cm^(2)

Area of bottom = length * breadth

= 12* 3

= 36 cm²

Area of left = 12 * 4

= 48 cm²

Area of right = 12 * 5 = 60 cm²

Total = 12 + 36 + 48 + 60 = 156cm²
