2 × pi × radius × height

What is Sphere with example?

The definition of a sphere is a ball shape where the surface is the same distance from the center at all points or a level of society. An example of a sphere is a globe. An example of a sphere is the upper crust or those in the highest levels of society.

How many circle make a sphere?

Infinite numbers of circles are needed to make one sphere. Since in between any two circles , one can draw another circle.

What is a formula of cylinder?

Solution. The formula for the volume of a cylinder is V=Bh or V=πr2h . The radius of the cylinder is 8 cm and the height is 15 cm. Substitute 8 for r and 15 for h in the formula V=πr2h .

What is the length of sphere?

Both sphere size and surface area can be easily calculated if you know the radius or diameter of the sphere. The formula for volume is 4/3 times pi times the radius cubed, or 4/3πr^3. The formula for surface is 4 times pi times the radius squared, or 4πr^2.

What is area formula?

The formula is: Area = w × h. w = width. h = height.

What is Sphere diagram?

Sphere Formulas – Surface Area of a Sphere Formula A sphere is a 3D object which can be defined as the collection of all the points in space that are equidistant from a given fixed point known as the centre. The following diagram shows a general sphere of radius r units with centre O.

How many sides has a sphere?

A sphere is a solid figure that has no faces, edges, or vertices. This is because it is completely round; it has no flat sides or corners. A cone has one face, but no edges or vertices. Its face is in the shape of a circle.

How many faces has a sphere?

A sphere has no faces, a cone has one circular face, and a cylinder has two circular faces. Therefore, the number of faces increases by one from one figure to the next. This is a pattern.

Can a sphere be flat?

Perfect sphere, the reason you can’t physically flatten a sphere, is because all of that third dimension of space has to go SOMEWHERE, so it’s either going to fall apart, and split the third dimension perfectly (EXTREMELY unlikely) or, it’ll stay together, and become deformed.

How many points define a sphere?

four points

Equation of vertical line

How do you write an equation for a vertical and horizontal line? Horizontal lines go left and right and are in the form of y = b where b represents the y intercept. Vertical lines go up and down and are in the form of x = a where a represents the shared x coordinate […]

Bernoulli’s equation example

What does Bernoulli’s equation State? Bernoulli’s principle states the following, Bernoulli’s principle: Within a horizontal flow of fluid, points of higher fluid speed will have less pressure than points of slower fluid speed. Why is Bernoulli’s equation used? The Bernoulli equation is an important expression relating pressure, height and velocity of a fluid at one […]
