Volume of Cones

Front

What is the formula for the volume of a cone?

Back

The volume V of a cone is given by the formula V = (1/3)πr²h, where r is the radius of the base and h is the height.

What does the term 'radius' mean in the context of a cone?

Back

The radius is the distance from the center of the circular base of the cone to its edge.

Front

What is the height of a cone?

Back

The height of a cone is the perpendicular distance from the base to the apex (the top point) of the cone.

Front

If a cone has a diameter of 10 cm, what is its radius?

Back

The radius is half of the diameter, so the radius is 5 cm.

If a cone has a height of 10 inches and a radius of 2 inches, what is its volume?

Back

V = (1/3)π(2)²(10) = (1/3)π(4)(10) = (40/3)π ≈ 41.89 inches³.

What is the volume of a cone with a base radius of 6 cm and a height of 9 cm?

Back

V = (1/3)π(6)²(9) = (1/3)π(36)(9) = 108π cm³ ≈ 339.12 cm³.
