What is the volume and surface area of a cylinder?

Answer: The volume of a cylinder can be calculated using the formula SA=2πr2+2πrh. A cylinder consists of two circles and one rectangle. The surface area of a circle is found using the formula πr2,so 2πr2 will allow us to find the surface area of the top and bottom faces of the cylinder.

How do you find cubic feet of a cylinder?

The volume of a cylinder in cubic feet is equal to π times the radius in feet squared times the height in feet. π is roughly equal to 3.14159265359.

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

From the volume of cylinder formula, we can find the radius of the 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 the volume of a cylinder?

Volume Of A Cylinder Volume of a Cylinder The volume of a cylinder is the density of the cylinder which signifies the amount of material it can carry or how much amount of any material can be immersed in it. Cylinder’s volume is given by the formula, πr2h, where r is the radius of the circular base and h is the height of the cylinder.

How do you find the radius of a cylinder?

We know from the formula of cylinder; Volume, V = πr 2 h cubic units. So, 440 = (22/7) × r2 × 35. r 2 = (440 × 7)/ (22 × 35) = 3080/770 = 4. Therefore, r = 2 cm. Therefore, the radius of a cylinder = 2 cm.

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.

What does the R stand for in the cylinder height formula?

R stands for the external radius. r stands for the internal radius. h stands for cylinder height. And now that we have it’s the formula, why not calculate it with hypothetical values for its variables.
