Find the volume of a cylinder with a radius of 3 cm and a height of 7 cm. a) 9π cm3 b) 21π cm3 c) 42π cm3 d) 63π cm3

Option (D) is correct.

The volume of given cylinder is 63π cm³

Step-by-step explanation:

Given : a cylinder with a radius of 3 cm and a height of 7 cm.

We have to find the volume of the given cylinder.

Consider the given cylinder with a radius of 3 cm and a height of 7 cm

We know,

Volume of cylinder =

Where, r is radius

and h is height

Substitute, h = 7 and r = 3

We have,

Volume of cylinder =

Simplify, we have,

Volume of cylinder =

Volume of cylinder =

Thus, The volume of given cylinder is 63π cm³

step-by-step explanation:

∆abc has the points a(1, 7), b(-2, 2), and c(4, 2) as its vertices. formed with the point d(1, 2) as its third vertex, then ∆abd is triangle.
