Question

Find the volume, curved surface area and total surface area of each of the cylinders whose dimensions are : Radius of the base =7cm and Height =50cm​

Answer 1

Answer:

The volume will be 7700cm^3

The curved surface area will be 2200cm^2

The total surface area will be 2508 cm^2

Explanation:

i. Volume of the cylinder =

$\pi r ^{2} h$

So, Volume = 22/7 * 7 * 7 * 50

= 22 × 350

= 7700cm^3

ii. C . S . A. of the cylinder =

$2\pi \: rh$

Hence, C.S . area = 2 × 22/7 × 7 × 50

= 100 × 22

= 2200cm^2

iii. T.S.A or total surafe area of the cylinder =

$2\pi \: r (r + h)$

Thus, Total surface area = 2 × 22/7 × 7 (7+50)

= 44 × (57)

=2508cm^2

That's all.
