Question

The total surface area of a solid cylinder of radius 8 cm and height 14 cm is ______ cm². i. 352 π

Answer 1

Given

Radius of the cylinder = 8 cm

Height of the cylinder = 14 cm

SOMETHING YOU NEED TO KNOW

CSA of a cylinder = 2πrh

TSA of a cylinder = 2πr(r+h)

Volume of a cylinder = πr²h

$\implies 2\pi r(r+h)\\\implies 2 * \pi * 8 (8+14)\\\implies 2 * \pi *8 * 22\\\implies 352\pi$

$\boxed{\boxed{\bold{Therefore. \ the \ TSA \ of \ a \ cylinder \ is \ 352\pi }}}}}$

QUESTION -

The total surface area of a solid cylinder of radius 8 cm and height 14 cm is ______ cm². i. 352 π

SOLUTION -

From the above question, we can derive the following information....

The radius is the required cylinder is 8 cm.

The height of the cylinder is 14 cm.

From the only option given [ Probably Typing Error ] we can get the information as to keep the answer in terms of the arbitrary constant π instead of an approximate value of it .

We know that -

The TSA of a cylinder is :

2 π r ( h + r )

=> 2 π 8 ( 8 + 14 )

=> 22 × 16 π

=> 352 π cm ^ 2.

So the only option given is the right answer.

So, option I. Is the correct choice...
