Question

The radius of the base of a cylinder is 2.1 cm and height 5 cm, then its volume is:
(a) 22.05
(b) 7.35 1
(c) 21 π
(d) None of theseרונן​

Answer 1

Answer:

d) None of these

Step-by-step explanation:

The radius of the base of a cylinder is ( r )=2.1 cm

Height of the cylinder ( h )= 5 cm

we know, The volume of the cylinder is ,

V = π r^2 h

[ Put the radius and height in the equation]

Solutions,

V = π r^2 h

or, V = π (2.1)^2 (5) cm^3

or, V= 69.27 ( approximately)

The volume of the cylinder is 69.27 cm.
