Question

Find the difference in the volume and total area of a cylinder with both a radius and height of 1.

Answer 1

I think its 2pi hope it helps

Answer 2

Answer:

The difference in the volume of cylinder and total surface area of cylinder =$3\pi$.

The number of sq units of total area exceeds the number of cu.units in the volume $3\pi$.

Step-by-step explanation:

Given radius of cylinder =1 unit

Height of cylinder= 1 unit

We know that  formula of volume of cylinder = $\pi r^{2} h$

Where r= Radius of  the cylinder

            h= Height of the cylinder

By using this formula  we can  find the volume of cylinder

 volume of cylinder =$\pi \times 1\times 1$ =$\pi cubic units.Formula of total surface area of cylinder: Total surface area of cylinder = [tex]2\pi r(r+h)$

By using this formula we can find total surface area of cylinder

 Total surface area of cylinder = $2\pi \times 1(1+1)[/tex} Total surface area of cylinder=[tex]4\pi$ sq units .

Difference between volume of  cylinder and total surface  area of cylinde= $4\pi -\pi$=$3\pi$

Total surface area of cylinder  - volume of cylinder=$3\pi$

Total surface area of cylinder = $3\pi$ + volume of cylinder

Hence, the number of sq units of total surface area exceed the number of cu.units in the volume by $3\pi$.
