Volume of Cylinders and Cones

Front

What is the formula for the volume of a cylinder?

Back

Volume = πr²h, where r is the radius and h is the height.

Front

What is the formula for the volume of a cone?

Back

Volume = (1/3)πr²h, where r is the radius and h is the height.

Front

What is the value of π (pi) used in calculations?

Back

Approximately 3.14.

Front

What is the circumference of a circle?

Back

The distance around a circle, calculated as Circumference = 2πr or πd, where r is the radius and d is the diameter.

Front

What is the radius of a circle?

Back

The distance from the center of the circle to any point on its circumference.

Front

What is the diameter of a circle?

Back

The distance across the circle through its center, equal to 2 times the radius.

Front

How do you calculate the circumference of a circle with a radius of 6 m?

Back

Circumference = 2π(6) = 12π ≈ 37.68 m.

Front

If the radius of a cone is 3 inches and the height is 4 inches, what is its volume?

Back

Volume = (1/3)π(3)²(4) = 12π ≈ 37.68 cubic inches.

Front

What is the relationship between the radius and diameter?

Back

Diameter = 2 × Radius.

Front

What is the area of a circle?

Back

Area = πr², where r is the radius.
