find the volume to surface area ratio for a cylinder use 1.7 as the radius and 3 for the height show your calucations

Question

please help me

Answer 1

The volume of a cylinder is

V = πr²h

 

 

The surface area of the same shape is

SA = 2πr² + 2πrh

SA = 2πr(r + h)

 

 

If we divide V by SA to get a simplified ratio, we get

 

V / SA = (πr²h) / [2πr(r + h)]

 

V / SA = rh / [2(r + h)]   ---->  simplified ratio

 

 

where:

r = radius = 1.7

h = height = 3

 

 

All you have to do is plug in the given values of radius and height into this simplified formula of the ratio.
