Question

find the volume of a cone if the diameter of the cone is 12.4 cm and the height of the cone is 30cm​

Answer 1

Answer:

Step-by-step explanation:

Given,

diameter of a cone = 12.4 cm

radius = diameter/ 2 = 12.4/2 = 6.2 cm

Volume of a cone = 1/3  x pie x r^2 x h

                        h = 30 cm

volume = 1/3 x 22/7 x (6.2)^2 x 30

            = 10 x 22/7 x 38.44

            = 1208.11 cm^3

           

Answer 2

Answer:

1208.11 cm³ ( option c )

STEP BY STEP EXPLANATION

=> Given : radius of cone = d/2 = 12.4/2 = 6.2 cm.

height of cone = 30 cm.

To find : volume of cone

SOLUTION -

As we know volume of cone = 1/3 πr²h

= 1/3 × 22/7 × (6.2)² × 30

= 1208.11cm³

HOPE THIS HELPS YOU........ .
