Question

The ratio between CSA and TSA of a right circular cylinder is 1:2. Find the volume of the cylinder​

Answer 1

Answer:

Volume of cylinder is 1078 cubic. cm

Step-by-step explanation:

If TSA is 616 sq.cm, then CSA will be 616/2 = 308 sq.cm. (ratio is 1:2)

TSA = 2*22/7*r*h + 2*22/7*r*r

Substituting 2*22/7*r*h as CSA, we get 308 + 2*22/7*r*r = 616 sq.cm

Therefore,  2*22/7*r*r = 616-308 = 308

Therefore, 2*22/7*r*r = 308

r*r = (308*7) / (2*22)

r*r = 49, r = 7 cm

To find h,

2*22/7*7*h = 308 sq.cm. (CSA)

​44h = 308, h = 308/44

h = 7cm

Now, volume = 22/7*r*r*h

= 22/7*7*7*7

Volume of cylinder is 1078 cubic. cm
