What is the circumference of 23?
The circumference of a circle is given by the formula 2πr, where r is the radius of the circle. Since no radius is provided in this case, the circumference of 23 cannot be determined.
What is the distance around a circle with a diameter of 18 inches?
The distance around a circle is called the circumference. The formula for the circumference of a circle is C = πd, where C is the circumference, d is the diameter, and π is approximately 3.14159. For a circle with a diameter of 18 inches, the circumference would be C = π(18) = 56.5487 inches.
What is the formula for finding the area of base of a cylinder?
The circumference of a regular cylinder is the circumference of its circular face. C = pi * D (diameter of the cylinder) C = pi * 2r (or C = 2(pi)r)
Whats pi equal to?
Pi is a mathematical constant that is approximately equal to 3.14159. It is the ratio of a circle's circumference to its diameter.
How do you estimate the circumference?
Just look at it clearly keep a ruler and works doneTo estimate multiply diameter by 3 and add 15% ormultiply the diameter by 22 and divide that by 7.Just multiply the diameter by 3 for a good estimation.
