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

First, measure the height h and diameter d of your cylinder. The diameter d = 2 times the radius r, d = 2*r. In the diagrams, h is the height of the cylinder and the cone, and r is the radius of their bases, which are equal. The circumference C of a circle is C = 𝜋d or C = 2𝜋r.

What is the curved surface area of cylinder?

2πrh
The radius ‘r’ of a cylinder is the radius of its base. Now, the area of the rectangle = length × breadth. 2πr is the circumference of the circle and h is the height. Area of the curved surface will be = 2πr × h = 2πrh.

How do you find the total surface area of a cylinder?

The formula to calculate the total surface area of a cylinder is given as, the total surface area of cylinder = 2πr(h + r), while the curved surface area of cylinder formula is, curved/lateral surface area of cylinder = 2πrh, where ‘r’ is the radius of the base and ‘h’ is the height of the cylinder.

What is the diameter of a cylinder?

2R
The diameter, or the distance across a cylinder that passes through the center of the cylinder is 2R (twice the radius).

What is the dimension of cylinder?

three-dimensional
A cylinder is a three-dimensional figure like a prism, but with bases that are circles.

What is the base of cylinder?

Circle
Cylinder/Base shape

What is base radius of a cylinder?

The radius of the cylinder is the radius of a base. The altitude of the cylinder is a perpendicular segment from the plane of one base to the plane of the other and the height of the cylinder is the length of the altitude. The axis of a cylinder is the segment containing the centers of the two bases.

How do you find the diameter of a base?

Root Diameter (df) is the diameter of the root circle; its value is: df = m (z – 2.5) or df = de – 2h. Center Distance (dc) is the distance between the shafts of the gear and the pinion; its value is: dc = (D + d) / 2, where “D” corresponds to the pitch diameter of the gear and “d” to the pitch diameter of the pinion.

What is the surface area of a cylinder with base radius 2cm?

Question: What is the surface area of a cylinder with the base radius r = 2 cm and the height h = 3 cm? Answer: The base surface area equals 25.133 cm², the lateral surface area equals 37.7 cm², and the total surface area equals 62.83 cm².

What is the diameter of a 42 cm cylinder?

The diameter of a cylinder is 42 cm and its height is 10 cm. The curved surface area = 2πrh = 2*22*21*10/7 = 1320 sq cm.

What is the height of a right circular cylinder?

The height of a right circular cylinder is 10.5 cm. If three times the sum of the areas of its two circular faces is twice the area of the curved surface area. Find the radius of its base.

How do you find the length of a cylindrical road?

1. Find the curved surface area and total surface area of a cylinder, the diameter of whose base is 7 cm and height is 60 cm. 2. The curved surface area of a cylindrical road is 132 cm2. Find its length if the radius is 0.35 cm. ∴ Length of road is 60 cm.
