What is the volume of a cylinder if the radius is 2?

Correct answer: The equation for the volume of the cylinder is πr2h. When the radius doubles (r becomes 2r) you get π(2r)2h = 4πr2h.

Which has a greater volume a cone of a cylinder?

Let’s fit a cylinder around a cone. So the cone’s volume is exactly one third ( 1 3 ) of a cylinder’s volume.

What is the volume if the radius is 2?

Volume Formula of a Sphere V=43πr3 , where r is the radius. V=43π(2)3=323π .

How many times greater is the volume of the cylinder compared to the volume of the cone having the same base and the same height?

The volumes of a cone and a cylinder are related in the same way as the volumes of a pyramid and a prism are related. If the heights of a cone and a cylinder are equal, then the volume of the cylinder is three times as much as the volume of a cone.

What is the relationship between volume of cylinder and cone?

What is the relationship between the volume of the cone and the volume of the cylinder? (Answer: The cone takes up one-third of the volume of the cylinder.)

How do you find the volume of a cylinder with radius?

For any cylinder with base radius ‘r’, and height ‘h’, the volume will be base times the height. Therefore, the cylinder’s volume of base radius ‘r’, and height ‘h’ = (area of base) × height of the cylinder. Since the base is the circle, it can be written as. Volume = πr 2 × h

What is the volume of a hollow cylinder in cubic units?

Therefore, the cylinder’s volume of base radius ‘r’, and height ‘h’ = (area of base) × height of the cylinder Therefore, the volume of a cylinder = πr2h cubic units. In case of hollow cylinder, we measure two radius, one for inner circle and one for outer circle formed by the base of hollow cylinder.

What is the radius of a cylinder of 440 cm3?

(Take pi = 22/7) Question 2: Calculate the radius of the base of a cylindrical container of volume 440 cm3. Height of the cylindrical container is 35 cm. (Take pi = 22/7) Therefore, the radius of a cylinder = 2 cm.

How to find the height of a cylinder in radians?

If you have the surface area and radius (r): 1 Make sure the surface and radius are in the same units and radius in is radians. 2 Subtract 2πr² from the surface area. 3 Divide the result of step 1 by 2πr. 4 The result is the height of the cylinder.
