The cylinder is a three dimensional solid having two parallel circles of the same radii on top and bottom and two vertical lines that join those circles. The center of circular bases overlaps each other to form a right cylinder. The line segment joining those two centers is the axis, that denotes the height of a cylinder.

Solved Examples on Cylinder

Example 1: Compute the circular cylinder height, volume, circumference, top surface area, base surface area, and total surface area? The cylinder radius is 5 cm, the lateral surface area is 314 cm².

Solution:

Given that,

Cylinder radius r = 5 cm

Lateral surface area L = 314 cm²

Height h = L / 2πr

= 314 / 31.4 = 10 cm

Circumference C = L

C = 10 cm

Top and Bottom Surface Area = T = B = L² / 4π

= 314² / 4π

= (314 * 314) / (4 * 3.14)

= 98,596 / 12.56 = 7,850 cm²

Total Surface Area A = L + T + B = L + L² / 2π

A = 314 + 314² / 2π

= 314 + (314 * 314) / (2 * 3.14)

= 314 + 98,596 / 6.28 = 314 + 15,700

= 16,014 cm²

Volume V = (L² * h) / 4πr²

V = (314² * 10) / (4 * 3.14 * 5²)

= (314 * 314 * 10) / (4 * 3.14 * 5 * 5)

= (98,596 * 10) / (314)

= 985960 / 314 = 3,140 cm³

∴ Circular Cylinder volume is 3,140 cm³, total surface area is 16,014 cm², top, base surface area is 7,850 cm², circumference is 10 cm, lateral surface area is 314 cm², height is 10 cm, and radius is 5 cm.

Example 2: If the cylinder radius is 9 m, and the volume is 6,104 m³. Find the cylinder height, lateral surface area, top, base surface area, total surface area, and circumference.

Solution:

Given that,

The radius of the cylinder r = 9 m

Volume V = 6,104 m³

Height h = V / πr²

h = 6,104 / ( 3.14 * 9²)

= 6,104 / ( 3.14 * 9 * 9)

= 6,104 / (254.34)

= 23.9 m

Lateral Surface Area L = 2πrh

L = 2 * 3.14 * 23.9

= 150.092 m²

Top Surface Area T = πr²

= 3.14 * 9²

= 3.14 * 9 * 9 = 254.34 m²

Bottom Surface Area B = πr²

= 3.14 * 9² = 254.34 m²

Total Surface Area A = L + T + B = 2πrh + 2(πr²)

A = 2πrh + 2(πr²)

= 2 * 3.14 * 9 * 23.9 + 2(3.14 * 9²)

= 1,350.828 + 2(254.34)

= 1,350.828 + 508.68 = 1,859.508 m²

Circumference C = 2πr

C = 2 * 3.14 * 9

= 56.52 m

∴ Circular Cylinder radius is 9 m, height is 23.99 m, the volume is 6,104 m³, the total surface area is 1,859.508 m², top, the base surface area is 254.34 m², circumference is 56.52 m, the lateral surface area is 150.092 m².

FAQs on Cylinder Calculator

1. What is the formula for finding the surface area of a cylinder?

To get the total surface area of a cylinder, you must calculate the lateral surface area and top, base surface area. Circular cylinder total surface area formula is A = 2πr(h+r). Here r is the radius, and h is the height.

2. How do you find the diameter of a cylinder?

The formula to compute the cylinder volume V = πr²h

Divide both sides of the equation by πh

(V / πh) = πr²h / πh

V / πh = r²

Apply square root to both sides.

r = √V / πh

As the diameter is double the radius

d = 2 * √V / πh

3. What is the definition of a cylinder?

A cylinder is a three-dimensional shaped object consisting of two parallel circular bases joined by a curved surface. The center of the circular base overlaps each other to form a right cylinder. the line segment joining two centers is the axis, called the height.

4. What are the properties of the cylinder?

Cylinder properties are mentioned here.

  • Bases are always congruent and parallel.
  • If the axis forms a right angle with bases, which are exactly over each other, then it is the right cylinder.
  • If bases are in a circular shape, then it is right circular cylinder.
  • If the bases are in an elliptical shape, then it is an elliptical cylinder.
