Question

the ratio between the curved surface area and the total surface area of a ritht circular cylinder is 1:2.if the total surface area is 616cm.find the volume of the cylinder​

Answer 1

Step-by-step explanation:

1-find the curved surface area and radius is come out and then volume of cylinder

Answer 2

Answer:

359.33 cm^3

Step-by-step explanation:

csa:tsa =1:2

csa/tsa =2πrh/2πr(h+r)

1/2 = h/h+r

h+r = 2h

r = 2h-h

r = h

since r = h substitute h=r in tsa formula.

2πr(r+r)=616

2πr(2r) = 616

2*22/7*r*2r =616

r^2= 616*7/44*2

r= 7=h

substituting 7 in volume formula 1/3πr^2h you will get 359.33
