How do you find out the area of a 3D circle?
The area of a sphere is 4πr2.
Volume of a circle?
Technically, a circle is a 2-dimensional object, so the question should read "volume of a sphere" OR "Area of a circle". The formula to work out the volume of a sphere is: 4/3 pi x r3, where "r" is the radius of the sphere. To find the area of a circle: pi x r2.
HOW TO find the volume of a circle?
The area of a circle is 'pi' multiplied by the square of the circle's radius.The volume of a circle is zero.The volume of a sphere is (4/3 pi) multiplied by the cube of the sphere's radius.
What is the largest circle that can be drawn around a sphere such as a globe?
That's called a "great circle" of the sphere. -- It's any circle whose center is at the center of the sphere. -- Its diameter is equal to the diameter of the sphere. -- Its area is equal to 1/4 the surface area of the sphere. -- The shortest distance between any two points on the sphere is along the piece of the great circle on which they lie. (There's only one, unless the two points are the opposite ends of a diameter.)
How is a circle and a sphere difrrent?
A sphere is three dimensional, a circle is not. So a tennis ball is sphere not a circle You can draw a circle on paper but is is not a sphere.
