Step-by-step explanation:The ratio between the curvedsurface area and total surface of right circular cylinder is 2:3 Find the ratio between the radius and height of the cylinder

2pir/2pir[h=2r]=2/3

3h=2r=2

3h-2=2

1;2 ratio

Answer 2

the CSA is 2πrh=2x

the TSA is 2πr(r+h)=3x

CSA-TSA = 2πr^2=x

r =√x/2π

h=2x/2πr

=2x/2π√x/2π

=2x/√2πx

=√2x/π

r/h=√x/2π/2x/π

=√1/2/2

=√1/4

r/h=1/2

r:h=1:2
