How do you find the diameter of a circular object?

Measure just the radius of the circle if it is very large. The radius is the distance from the center to any point on the circle. Multiply the radius by two to produce a measurement for the diameter.

How do you measure the diameter of a steel ball?

The diameter of a steel ball is measured using Vernier calipers which has divisions of 0.1 cm on its main scale (MS) and 10 divisions of its Vernier scale (VS) match 9 divisions on the main scale.

What is the diameter of a beach ball in CM?

Diameter of the beach ball is 42 cm .

How does a beach ball get its shape?

Design. Beach balls range from hand-sized to over 3 feet (0.91 m) across or larger. They generally have a set of soft plastic panels, with two circular end panels, one with an oral inflation valve, intended to be inflated by mouth or pump. A common design is vertical solid colored stripes alternating with white stripes …

How do you find the diameter of the ball in vernier caliper?

Procedure

1. Determine the vernier constant (V.C.)
2. Bring the movable jaw BD in close contact with the fixed jaw AC and find the zero error.
3. Open the jaws, place the sphere or cylinder between the two jaws A and B and adjust the jaw DB, such that it gently grips the body without any undue pressure on it.

How is the diameter of a spherical body measured for Class 7?

A vernier scale or a vernier calliper is a measuring device that is used to precisely measure linear dimensions. It is a useful tool to measure spherical and cylindrical objects. It has two main scales known as the main scale and the vernier’s scale, which are divided into small divisions.

What shape is a beach ball?

Measurement takes in to consideration the following: In the plant, the beach ball will loose some length at each end. They do this so when inflated, the ball is round and not egg shaped. The beach ball will loose some length during inflation as it goes from long to round.
