Best Answer

Volume of a cylinder is given by the formula: V = πr2h

It is important to keep in mind that:

If r is doubled then volume becomes four times....(1)

Volume of the cylinder with radius of 2.5 units is equal to π(2.5)2h and volume of the cylinder with radius of 5 units is equal to 4π(2.5)2h. (By using the fact (1))

So, it is clear that volume of the cylinder with greater radius is 4 times the volume of the cylinder with smaller radius.

How many times greater is the volume of a cylinder if you double the radius?

i think its the same since the radius is half the diameter.


How do you find the radius and the height for a cylinder when giving its volume?

the volume of a cylinder equals pi times the radius squared times the height. If you have the volume, you can't know the radius or the height, only their proportional value. You need more information


What is the formula for the area of a circle and the volume of a cylinder are related?

The formula for area of a circle is radius squared times pi. The formula for volume of a cylinder is radius squared times pi times height.


What is pi times the radius squared times the height?

This is the volume of a cylinder.


What is the height of a cylinder when only given the volume and radius?

Since the formula for the volume of a cylinder is PI time the radius squared times the height we can calculate the height from the other two values. The height is the volume divide by PI times the radius squared.


How do you calculate volume of cylindrical storage tank?

pi times the square of the cylinder radius times the cylinder height.


The volume of a cylinder increased by 8 times the original volume How many times greater are each of the dimensions of that new cylinder?

the dimensions of the cylinder would be 2 times greater. We just had a test on this stuff and this was one of the questions.


Formula for volumn of a cylinder?

For a right cylinder, the formula for volume is quite simple. It is pi times the radius of the cylinder squared times the height of the cylinder.


How do you find the height of the volume of horizontal cylinder?

The height of a horizontal cylinder is 2 times its radius.


What is the formula for volume for a cylinder?

What is the new volume of a cylinder if the height and radius are doubled?

If the radius and height of a cylinder are both doubled, then its surface area becomes 4 times what it was originally, and its volume becomes 8 times as much.


What is the effect on the volume of a right cylinder if its radius is tripled?

The volume increases to 9 times as much.


How do you find the radius of big cylinder given radius of small cylinder and big cylinder is 4 times larger than the small cylinder?

The answer will depend on whether the larger cylinder is 4 times larger in terms of radius, cross-sectional area, or volume. If radius, multiply the smaller radius by 4. If cross-sectional area, multiply the smaller radius by 2. If volume, you do not have enough information.


If the height and radius of a cylinder are doubled how will the volume of the cylinder be affected?

volume is related as radius squared x height soif both radius and height doubled volume increases 2 x 2 x 2 = 8 times


What is the formula for the weight of a cylinder?

The volume of a cylinder is three times as much.


What is radius squared times height?

If you multiply that by Pi, you'll get the volume of a cylinder.


What is formula for the volume for a cylinder?

The volume of a cylinder is pi times R2 times H. pi is approximately 3.14159 R = the radius of the base (circular end) of the cylinder H = the height (length) of the cylinder As related to automobile engines... the length of the cylinder is the "stroke" of the engine or the radius of the crankshaft throws multiplied by 2


How do you calculate the volume in liters of a cylinder radius 27.94cm and length 86.36cm?

The volume of a cylinder equals pi times the radius squared times the length, and there are 1000 cubic centimeters in a litre. Thus, 211.69 litres.


How do you prove that a cone will fit into a cylinder exactlly 3 times?

If you look at the formulas for volume of a cone and volume of a cylinder you can see that a cone will fit in exactly three times if the height and radius of the cone and cylinder are equivalent. A cone has the equation: (1/3)*pi*(r^2)*h=Volume. And a cylinder has the equation: pi*(r^2)*h=Volume. With h equaling height and r equaling radius, you can see that 3*(Volume of a cone)=Volume of a cylinder. Therefore, the cone would fit in three times if height and radius are equivalent for the two figures.


Why is the Volume of a cone Pi times Radius times Radius times height?

Actually it isn't. That's the formula for a cylinder. A cone is 1/3 of that value.


How do you find the volume of cylinder?

Let's pretend the radius of the cylinder's circular base is 4. You need to square the radius of the base first. In this case, we will do 4x4 which is 16. (4x4=radiusxradius). Next, you will do 16 (radius times radius) multiplied by pi. In our example, the we will do 16 times pi which is 50.26548246. Now, let's pretend the height of the cylinder is 7. We will multiply 50.26548246 by 7 and get 351.8583772. This is the volume of our cylinder.


If the dimensions of a cylinder are doubled will the volume be 8 times greater?

Yes.
