Question

a 06 Find the height of a cylinder with a surface area of 1081 square meters. The radius of the cylinder is twice the height​

Answer 1

Answer:

Total surface area of cylinder = 2pir(r+h)

but r= 2h

SA = = 2pi*2h(2h+h)

=12pih^2

108=6pih^2

108/12 = pi h^2

108/(12*pi)=h^2

h=1.69

Check

2*pi*3.38(1.69+3.38)
