Question

The total surface area of a cylinder is 462 cm square its csa is one third of the tsa find its volume

Answer 1

Answer:

Step-by-step explanation:

TSA of a cylinder=2πr(h+r)

CSA=2πrh

2πrh=1/3[2πr(h+r)

3h=h+r

3h-h=r

2h=r

TSA=2πr(h+r)

=2*22/7*2h(h+2h)

462=2*22/7*h*3h

462/44*3=h^2

3.5=h

Volume=πr^2h

Volume=22/7*(2*3.5)^2(3.5)

=539cm^3
