# What is the radius of a cylinder with a diameter of 18? ### What is the radius of a cylinder with a diameter of 18?

Answer: 9cm. Step-by-step explanation: A diameter is twice the length of a radius.

### How do you find the radius of a cylinder from the diameter?

0:384:57How to find the Height and Radius of a Cylinder given the Volume ...YouTubeStart of suggested clipEnd of suggested clipAnd then the green line here that goes all the way across through the center of the circle from oneMoreAnd then the green line here that goes all the way across through the center of the circle from one side to the other that's called the diameter. And the diameter is twice the distance of the radius.

### What is the radius of a cylinder?

The radius of a cylinder(r) = √(V / π × h), where V is the volume of a cylinder, h is the height of the cylinder, and π(Pi) is a mathematical constant with an approximate value of 3.14.

### What is a formula of cylinder?

The formula for the volume of a cylinder is V=Bh or V=πr2h . The radius of the cylinder is 8 cm and the height is 15 cm. ... Therefore, the volume of the cylinder is about 3016 cubic centimeters.

### How do you find the radius of a cylinder calculator?

Below, we have listed six basic equations that can be used to derive the explicit formulas of radius of a cylinder:

1. Volume of a cylinder: V = π * r² * h ,
2. Base surface area of a cylinder: A_b = 2 * π * r² ,
3. Lateral surface area of a cylinder: A_l = 2 * π * r * h ,
4. Total surface area of a cylinder: A = A_b + A_l ,

### How do you find the radius with height?

3:135:02How to Find Radius of a Cylinder from Given Volume and Height - YouTubeYouTube

### How do you find the height of a cylinder with only the radius?

First, plug the values of the volume, pi, and radius into the formula for volume of a cylinder. Next, square the radius and multiply the values together. Last, divide each side by 113.04 for the answer, remembering to include the appropriate unit of measurement. The answer is the height of the cylinder is 8 inches.

### How do you find the radius?

How to Find the Radius of a Circle?

1. When the diameter is known, the formula for the radius of a circle is: Radius = Diameter / 2.
2. When the circumference is known, the formula for the radius is: Radius = Circumference / 2π
3. When the area is known, the formula for the radius is: Radius = ⎷(Area of the circle / π)

### What is TSA of cylinder?

Total Surface Area of Cylinder The total surface area of a cylinder is equal to the sum of areas of all its faces. The Total surface area with radius 'r', and height 'h' is equal to the sum of the curved area and circular areas of the cylinder. TSA = 2π × r × h + 2πr2= 2πr (h + r) Square units.

### How tall is a cylinder and what is its radius?

A cylinder has radius 7 cm and height 10 cm.Find the volume of the cylinder. A cylinder has radius 7 cm and height 10 cm.Find the volume of the cylinder. Was this answer helpful?

### How to calculate the volume of a cylinder?

Cylinder Volumes = pi x radius squared x height. V = π r 2 h. Cylinder Volume = 3.14159265 x radius 2 x height. 1 cubic metre = 1000 litres.

### How big is a cylinder in cubic metres?

Cylinder Volume = 3.14159265 x radius 2 x height. 1 cubic metre = 1000 litres. 1 cubic centimetre = 1 millilitres.

### How to calculate the radius of a circle?

The diameter of a circle is the length of a straight line drawn between two points on a circle where the line also passes through the centre of a circle, or any two points on the circle, as long as they are exactly 180 degrees apart. This is the radius of a circle that corresponds to the specified diameter.
