How do you find the diameter of a cylinder from the area of the base?

The area of the base of a cylinder = Pi times Radius squared. Diameter of a cylinder = 2 times Pi times Radius. To find the diameter derive the area of the base by Pi and then square root the answer. That will give you the value of the radius. Multiply that answer by 2 times Pi and you will have your answer.


What is the area of the base of a cylinder that has a diameter of 12 inches?

The area of the base is approximately 113.1 square inches.


What is the liquid volume of pipe 140mm in diameter and 1mtr in length?

Volume of the cylinder = Area of the Base X Length Area of the Base = Area of a Circle = Pi X r2 where Pi = 3.1416 r = radius of the pipe = 70mm = 0.07mtr Therefore Volume of the Cylinder = 3.1416 x 0.0702 mtr x 1mtr = 0.01539m3


How do you find diameter of cylinder if pressure at base is given?

You can't. In addition to the cylinder's diameter, the pressure at its base also depends on the density and depth of the fluid in the cylinder ... which gives you the weight of fluid resting on the base area. The pressure alone is not enough information to allow you to calculate the diameter.


What is the surface area of a cylinder having a base diameter of 8 and a height of 10?

The curved surface area of this cylinder is 251.33 units2


What is the area of the base of the cylinder with the diameter of 8?

Diameter is 8, hence radius is 4the base of a cylinder is also a circle. so we take the formula for area of a circle which isπr23.14 x (4)2= 3.14x 16= 50.24


What is formula of cylinder if the base are given?

Neither the area or the volume of the cylinder can be calculated without the length.


How do you find the volume of a cylinder when given the diameter?

Stand it on a circular end, like a tin can standing on a shelf.Its volume is the area of its circular base, multiplied by its height.Another Answser:To answer the specific question, you can not find the volume of a cylinder when given only its diameter. You need also its length.


What is the formula for finding the area of base of a cylinder?

The circumference of a regular cylinder is the circumference of its circular face. C = pi * D (diameter of the cylinder) C = pi * 2r (or C = 2(pi)r)


What is the surface area of a cylinder with a base diameter of 12 and a height of 8?

The curved surface area is 301.6 units2


How do you get the area of a cylinder base in fifth grade math.?

The base of a cylinder is a circle. So we can use the area formula for a circle. Area = πr2 where r is the radius of the circle, and pi is the ratio of the circumference of the circle to its diameter.


What happens to the surface area of a cylinder if the height is doubled and the diameter of the base is not change?

The surface area of the 'wall' doubles, but the base areas remain the same.
