Question

Find the lateral area for the cylinder with the given measurement. r = 6, h = 20

Answer 1

Answer:

Lateral Area (L) of the cylinder is given by:

$L = 2 \pi rh$              ....[1]

where,

r is the radius of the cylinder

h is the height of the cylinder.

As per the statement:

Given:

r = 6 units , h = 20 units

Substitute the given values and use $\pi = 3.14$ in [1] we have;

$L = 2 \cdot 3.14 \cdot 6 \cdot 20$

Simplify:

$L = 753.6$ square units.

Therefore,  the lateral area for the cylinder with the given measurement is, 753.6 square units.

Answer 2

Pi(12) times 20 = 240pi+2(6pi^2)=312pi
