Which of the following is the surface area of the right cylinder below?

c. 198π units²

Step-by-step explanation:

We have to find the surface area of a cylinder.

We know that surface area of a cylinder= 2πrh+2πr²

where r is the radius

and h is the height of the cylinder.

here h=2 units and r=9 units

Surface area= 2π×9×2+2π×9×9

                   = 198π units²

Hence, correct option is:

 c. 198π units²

The surface area of the right cylinder is .

Further explanation:

The formula for the surface area of the cylinder can be expressed as,

Here, ‘r” represents the radius of the cylinder and “h” represents the height of the cylinder.

Given:

The radius of the cylinder is  and the height of the cylinder is  .

The options of surface area are given as follows.

A.  

B.  

C.  

D.

Explanation:

The surface area of the right cylinder can be obtained as follows,

The surface area of the cylinder is .

Option A is not correct as the surface area of the cylindrical is not .

Option B is not correctas the surface area of the cylindrical is not .

Option C is correct as the surface area of the cylindrical is .

Option D is not correct as the surface area of the cylindrical is not  .

Hence, the surface area of the right cylinder is .
