What is the formula of finding the circumference of a sphere?
4*pi*r2. because surface area is equal to circumference of circle.
How do you find the circumference of a sphere?
Circumference = π * Diameter
What does the diameter of the sphere join?
The diameter joins together the circumference of the sphere and it passes through the center of the sphere.
What is the distance around a sphere called?
The circumference.
How many angles of a sphere have?
The angles around the circumference of a sphere add up to 360 degrees.
What is the formula of finding the circumference of a sphere?
4*pi*r2. because surface area is equal to circumference of circle.
How do you Calculate circumference of a ball?
To calculate the circumference of a ball (which is a sphere), you use the formula for the circumference of a circle, ( C = 2\pi r ), where ( r ) is the radius of the sphere. If you have the diameter ( d ) instead, you can use the formula ( C = \pi d ), since the diameter is twice the radius (( d = 2r )). Simply plug in the radius or diameter into the appropriate formula to find the circumference.
What is the formula for finding the radius of sphere?
1/2 diameter or the circumference/pi/2
What is the surface area of a sphere with a circumference of 9cm?
You can divide this problem into two steps: 1) Divide the circumference by (2 x pi) to get the radius. 2) Use this radius in the standard formula for the surface area of the sphere.
What is the circumference of a sphere with a diameter of 20 inches?
The circumference of the sphere is ~62.831 inches.
What is the formula for finding perimeter of sphere?
A sphere does not have a perimeter. It can have a diameter a circumference or a surface area (or volume but that isn't discussed here.The diameter of a sphere is two times the radius (r): so the formula would be2r...or...2 x rThe circumference (C) of a sphere is equal to 6.2832 times the Radius, where 6.2832 is twice Pi (): so the formula would beC = 2r...or...C = 2 x x rThe area of a sphere is equal to the Square of the Radius of the sphere multiplied by 12.566 (4 times ): so the formula would be4 * * R * R
What is the cirucumference of an object with a diameter of 5?
Well, first of all, it has to be a circle or a sphere, otherwise it's perimeter, not circumference. But if your object is a circle or a sphere, the formula is C=pi x diameter. So the circumference of your object is 5pi
How do you work out the surface area of a sphere shape?
The area of a sphere is equal to its circumference times its diameter.There are a variety of ways to work out this formula, most of them involving calculus.(See the links for the volume of a sphere).
How do you find the circumference of a sphere?
Circumference = π * Diameter
What is the surface area of a sphere whose great circle has a circumference of 40pi?
The great circle has circumference 40pi and we know circumference is 2pixr so 20 is the radius of the sphere. Now use this and the formula that surface area is 4pir^2 so the surface are is 4pi(20)^2. or pi(1600)
What is diameter and circumference?
Diameter is distance across a circle or sphere, circumference is the distance around a circle or sphere
What does the radius of a sphere join?
The radius of a sphere joins the center of the sphere to its circumference.
