Question

calculate the curved surface area of a cylinder container with radius 30cm and height 36cm. take pie =3.14

Answer 1

Step-by-step explanation:

CSA = 2πrh

= 2*3.14*30*36 cm²

= 6782.40 cm²

Answer 2

According to the given details in above question

We have to find the curved surface area of cylinder container.

Step-by-step explanation:

Given ,

Radius of cylinder container = 30 cm

Height of cylinder container= 36 cm

The value of π or pie= 3.14

STEP-1:

The formula of curved surface area of cylinder container is 2πrh

where ,

r= radius

h = height

π= pie

STEP-2:

According to question , put the values in the formula

Curved surface area = 2πrh

$Curved \: surface \: area = \\ 2 \times 3.14 \times 30 \times 36 \: {cm}^{2}$

Multiply the terms

$CSA= 2 \times 3.14 \times 108 \: {cm}^{2}$

Again multiply remaining values ,

$CSA= 216 \times 3.14 \: {cm}^{2}$

$CSA= 216 \times \frac{314}{100} \: {cm}^{2}$

$CSA= \frac{67824}{100} \: {cm}^{2}$

$CSA= \frac{67824}{100} \: {cm}^{2}$

Divide by 100

$CSA= 678.24 \: {cm}^{2}$

Hence ,

The curved surface area of cylinder is 678.24 cm².
