A cylindrical can has a volume of 40p cm^3 and is 10 cm tall.

Question

what is the diameter of the cylindrical can?

Answer 1

Michelle,

 

The formula for the volume of a cylinder is V=pi*r^2*h where V=volume, r=radius, and h=height.

 

We can rearrange this formula to solve for r

 

r^2=V/(pi*h)

 

r=sqrt(V/(pi*h))

 

r=1.13 cm

 

d=r*2=2.26cm   where d=diameter
