Answer:
4:5
Step-by-step explanation:
reduce the 8 and 10 by dividing both by 2.
A=468in²
s/5=b
first sphere
volume = 113.142 m^3
2nd sphere
radius= 6 m
first cone
volume = 314.285 m^3
2nd cone
height=8 m
1st cylinder
volume=88 m^3
2nd cylinder
height=3m
C. 155.5 cm2
area = 5*15 + (15+8)*7/2 = 75 + 80.5 = 155.5 cm2
