Question

the radius of the base of a cone is 7 cm and height is 6 CM its volume is

Answer 1

the radius (r) = 7 cm
height (h) = 6 cm

so it's volume = 1/3 πr2h

1/3×π×6×6×7= 84πcm3


or 84×22/7=. 264 cm3

Answer 2

Given:

• The radius of the cone = 7 cm
• The height of the cone = 6 cm

To Find:

• The volume of the cone.

Solution:

• We know that the volume of the cone is given by,
• V = $\frac{1}{3}$ π$r^2$h → (1)  ( where 'r' is the radius of the cone and 'h' is the height of the cone)
• Substitute the values in equation (1) we get,
• The volume of the cone, v = $\frac{1}{3}$ * 3.14*(7*7)*6
• The volume of the cone, v = 308 $cm^3$
• The volume of the cone, v = 308 $cm^3$

∴The volume of the cone, v  = 308 $cm^3$
