Please help asap!!!!!!!! Number 2 and 3

Answer:
Step-by-step 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 = [tex]2* \frac{1}{2}*b * h\\[/tex]
[tex]= 2*\frac{1}{2} * 3 * 4\\\\= 12 cm^{2}[/tex]
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
