Question

Find the volume of cone whose diameter is 7cm and perpendicular height is 6cm to the nearest whole number

Answer 1

Answer:

Here is ur answer friend :)

Step-by-step explanation:

Hi friend,

Radius=6 cm

Height=7 cm

Volume of the cone= 1/3*pi*r^2*h

=1/3*22/7*6*6*7

=22*2*6

=22*12

=264 cm^2

Hope it helped you..............................

Answer 2

ANSWER :-

• Volume of cone = πr²h/3.

→Here, diameter = 7

∴ radius = D/2  = 7/2.

⇒  Volume = π(7/2)² / 3

              = [22/7  ×  7/2 × 7/2 ]/ 3

                =  77/6  = 12.8

               ≅ 13.
