Question

A cylinder has a volume of 198 and base has an area of 22 what is the height o the cylinder

Answer 1

Answer:

Step-by-step explanation:

The base of the cylinder is in the shape of a circle:

Area of the base=$\pi *r^2$

For Base area=22 square units

$22=\pi *r^2$

      $22=3.14*r^2\\r^2=22/3.14\\r^2=7.01\\r=\sqrt{7.01}$

Volume of the cylinder=$\pi *r^2*h$

For volume '198 cubic units' the height(h) is:

       $198=\pi *r^2*h$

       $198=3.14*(\sqrt{7.01})^2*h$

         $198=3.14*7.01*h\\\\198=22.01*h\\\\198/22.01=h\\\\h=9 units$
