a = 14°

b = 36°

Step-by-step explanation:

4b - 12 + 48 = 180 (supplementary)

Rearrange

4b = 180 - 48 + 12

4b = 144

b = 36°

4a - 8 + 4b - 12 = 180 (supplementary)

sub b = 36 into equation

4a - 8 + 144 - 12 = 180

Rearrange

4a = 180 - 144 + 12 + 8

4a = 56

a = 14°

area = 40 $\pi$ $m^{2}$

vol = 32 $\pi$ $m^{3}$

Step-by-step explanation:

area :

cir = 2 $\pi$ i 2 = 4 $\pi$

area = $\pi$ 2^2 = 4 $\pi$

2(4 $\pi$ ) + 8(4 $\pi$ )

8 $\pi$ + 324 $\pi$ = 40 $\pi$

vol = 8 * 4 $\pi$ = 32 $\pi$
