A car's engine has 6 cylinders, each of diameter 9.6 cm and height 10.4 cm. Find the capacity of the engine's cylinders in cc (cubic centimetres).

Answer 1

1.
2*12*8+2*8*h+2*12*h=324cm^2
solve and find h?

Answer 2

2.
no of cards = 6/(0.2*0.15)

Answer 3

3.
capacity= pi*(9.6/2)^2*10.4*6 cc

Answer 4

Thanks so much!
