Question

find csa of each of the cylinders R=xcm h= ycm​

Answer 1

Answer:

csa of a cylinder = 2×pi×radius×height

radius = x cm

height = y cm

cad of the cylinder = 2×22/7×x×y

=2×22×xy/7

=44xy/7

Answer 2

The CSA of the cylinder with radius x cm and height y cm is $\pi x^2/4$ square cm.

The CSA (cross-sectional area) of a cylinder is given by the formula:

$CSA = \pi r^2$

where r is the radius of the cylinder.

In terms of the given dimensions, we have:

r = x/2  (since the diameter of the cylinder is equal to x)

So, the CSA of the cylinder is:

$CSA = \pi (x/2)^2 = \pi x^2/4$

However, we also have the height of the cylinder, y. So, the volume of the cylinder is:

$V = CSA * h = \pi x^2/4 * y$

Therefore, the CSA of the cylinder with radius x cm and height y cm is $\pi x^2/4$ square cm.
