Question

The diameter of a cylinder 36 cm and height is 21 cm. Find its lateral surface area and volume of the cylinder. ( pi = 22/7)​

Answer 1

Answer:

Answer ⤵️

diameter of a cylinder =36 cm

the the height of cylinder 21 CM

as we know that

radius of cylinder= d/# =36/2=18cm

formula of:

latersal surface area of cylinder= 2πr

h

Volume of cylinder πr^2 h

using this formula in equation we get

=L.S.A =2×22/7×18×21

= L.S.A =2×22×18×3

= L.S.A = 2376 cm

then we find volume

volume=πr^2

volume 22/7×18×18×21

volume 21384 cm

Step-by-step explanation:

show that

lateral surface area of cylinder is

2376 cm

and the volume of cylinder

21384 CM

hope this helps you ✌️

Answer 2

$\large\tt\dag\underline\purple{To Find }:-$

LSA

Volume

$\large\tt\dag\underline\purple{Solution }:-$

For Radius

Radius = 36/2 = 18 cm

For LSA

$\sf LSA = 2\pi rhLSA=2πrh$

LSA = 2 × 22/7 × 18 × 21

LSA = 44/7 × 18 × 21

LSA = 44 × 18 × 3

LSA = 2376 cm²

For Volume

$\sf Volume = \pi r^2 hVolume=πr$

Volume = 22/7 × (18)² × 21

Volume = 22/7 × 324 × 21

Volume = 22 × 324 × 3

Volume = 66 × 324

$Volume = 21384 cm³\begin{gathered}\\\end{gathered}$
