Question

Find the total surface area of a cylinder with a height of 8 cm and radius of 4 cm. Leave your answer in terms of π.

Answer 1

Answer:

96π cm²

Step-by-step explanation:

Use the formula for the surface area of a cylinder:

A = 2πrh + 2πr²

Plug in the height and radius, and solve:

A = 2π(4)(8) + 2π(4)²

A = 2π(32) + 2π(16)

A = 64π + 32π

A = 96π

So, the surface area of the cylinder is 96π cm²

Answer 2

G I V E N :

Find the total surface area of a cylinder with a height of 8 cm and radius of 4 cm. Leave your answer in terms of π.

S O L U T I O N :

According to the question, here we have to find out the T.S.A. or the total surface area of the cylinder using a certain formula then put the respective values and get the result in terms of π

• T.S.A. of Cylinder = 2πr(h + r)

Here,

r represents radius

h represents height

Given Data :

Height = 8 cm

Radius = 4 cm

Using the formula we get

• T.S.A. = 2π × 4 cm(8 cm + 4 cm)

• T.S.A. = 8π cm(12 cm)

• T.S.A. = 96π cm²

Henceforth, the required answer is 96π cm²

2ND OPTION IS CORRECT i.e. 96π cm²
