Question

1. Find the volume of a cylinder, if the radius of the base and its height are as follows: (1) radius = 7 cm, height = 10 cm (ii) radius = 2 cm, height = 7 cm​

Answer 1

Step-by-step explanation:

(i) 1540cm³

(ii)88cm³

formula is 22/7*r²*h

Answer 2

Answer:

Answer of this question:

i) 1540 cm^3 and ii) 88 cm^3.

Step-by-step explanation:

Formula: Volume of a cylinder = πr^2h

i) radius = 7 cm, height = 10 cm

=> πr^2h => 22/7×(7)^2×10

=> 22×7×10 => 154×10 => 1540 cm^3

ii) radius = 2 cm, height = 7 cm​

=> πr^2h => 22/7×(2)^2×7 => 22×2×2

=> 22×4 => 88cm^3
