1.	The ratio between the curved surface and total surface of a cylinder is 1:2. Find thevolume of the cylinder, given that its total surface area is 616 cm
Answer» Step-by-step explanation: 2πrh/2πr(r+h)=1/2 h/r+h=1/2 cross multiply 2h=r+h r=h 4πrh=616 r=7 volume = π7^3 =1078cm^3

The ratio between the curved surface and total surface of a cylinder is 1:2. Find thevolume of the cylinder, given that its total surface area is 616 cm

Answer»

Step-by-step explanation:

2πrh/2πr(r+h)=1/2

h/r+h=1/2

cross multiply

2h=r+h

r=h

4πrh=616

r=7

volume = π7^3

=1078cm^3
