Answer:
area = 40 [tex]\pi[/tex] [tex]m^{2}[/tex]
vol = 32 [tex]\pi[/tex] [tex]m^{3}[/tex]
Step-by-step explanation:
area :
cir = 2 [tex]\pi[/tex]i 2 = 4 [tex]\pi[/tex]
area = [tex]\pi[/tex] 2^2 = 4 [tex]\pi[/tex]
2(4 [tex]\pi[/tex]) + 8(4 [tex]\pi[/tex])
8 [tex]\pi[/tex] + 324 [tex]\pi[/tex] = 40 [tex]\pi[/tex]
vol = 8 * 4 [tex]\pi[/tex] = 32 [tex]\pi[/tex]
