Question

The volume of cone with radius 2 cm and height 6 cm is ..... cm³.select a proper option (a), (b), (c) or (d) from given options so that the statement becomes correct.
(a) 8????
(b) 12????
(c) 14????
(d) 16????

Answer 1

Hi ,

Let r and h are radius of the base and

height of the cone

It is the given that ,

r = 2 cm , h = 6 cm , π = 22/7

Volume of the cone ( V ) = ( πr²h )/3

V = ( 22 × 2 × 2 × 6 )/( 7 × 3 )

V = 176/7 cm³

V ≈ 25.14 cm³

Options are wrong .

I hope this helps you.

V =

Answer 2

Given radius of cone(r) = 2 cm

and height of cone(h) = 6 cm

we, defined volume of cone v is $\frac{1}{3}\pi r^{2} h$

$v = \frac{1}{3} \pi *2^{2}*6$

hence, $v = 8\pi cm^{3}$

$v = 25.133 cm^{3}$
