Answer 1

You know the formula for calculating the lateral area of a cylinder with a radius r and height h is S=2*π*r*h
So we have S= 2*π*6*20= 240π
Have fun

Answer 2

Answer:

Option (b) is correct.

The lateral area for the given cylinder is $240\pi$ square units

Step-by-step explanation:

  Given: A cylinder with radius 6 units and height 20 units.

We have to fine the lateral area for the cylinder with the given measurement.

The lateral area for the cylinder is given by  $2\pi rh$

Put  r = 6, h = 20  

We have,

The lateral area for the given cylinder =$2\pi\cdot 6\cdot 20$

Simplify, we have,

The lateral area for the given cylinder = $240\pi$ square units
