Question

What is the surface area of a cylinder with base radius 2 and height 5? Either enter an exact answer in terms of \piπpi or use 3.14, for \piπpi and enter your answer as a decimal.

Answer 1

Answer:28pi

Explanation:

Answer 2

Surface Area of the cylinder is
`28\pi` Or 87.92 square units.

Explanation:

Given:

radius
`r` = 2

height
`h` = 5

We need to find the surface area of the cylinder.

Solution:

Now we can say that;

Surface Area of the cylinder is given by the formula.

`A=2\pi r(h+r)`

Now Substituting the given values we get;

`A=2\pi*2(2+5)\\\\A=4\pi*7\\\\A=28\pi \ \ \ \ Or \ \ \ \ 87.92`

Hence Surface Area of the cylinder is
`28\pi` Or 87.92 square units.
