what is surface area?

The surface area of a solid object is a measure of the total area that the surface of the object occupies.

100

what is volume?

Volume is a scalar quantity expressing the amount of three-dimensional space enclosed by a closed surface.

100

what is density?

the degree of compactness of a substance.

100

what is a sphere? 

A sphere is a geometrical object that is a three-dimensional analogue to a two-dimensional circle.

100

what is circumference angles?

An angle at the circumference of a circle is half the angle at the center standing on the same arc. - Two angles at the circumference standing on the same arc are equal.

200

what is the surface area formula?

1) SA=2B+Ph

2) SA=B+12sP

3) SA=2B+2πrh

200

how do you find the volume?

Volume = length x width x height.

200

what does density mean

Density is the number of things—which could be people, animals, plants, or objects—in a certain area.


200

What is the formula in finding the area of a sphere?

the formula for the surface area of a sphere of radius R is 4*Pi*R2.

200

How do you find an angle using the circumference?

radius is 5 so diameters 10 so the circumference is just simply 10 pi.

300

how do you find the surface area

 by adding all the areas on the surface: the areas of the base, top, and lateral surfaces (sides) of the object.

300

how do you solve for volume.

Box a rectangle a cylinder a cone and a sphere or a ball starting with a cube or square box the formula for calculating the volume of a cube is length times width times height.

300

how do you calculate density?

The Density Calculator uses the formula p=m/V, or density (p) is equal to mass (m) divided by volume (V). The calculator can use any two of the values to calculate the third. Density is defined as mass per unit volume.



300

What is the radius of a sphere?

The radius is half the diameter, so use the formula r = D/2.

300

What degree is circumference?

360 degrees. 

400

what is surface area of solid shapes.

The surface area of any solid shape is the sum of the areas of all faces in that solid shape. 


400

what is the volume of a cone

V=1/3hπr²


400

how do you get the formula of density

The formula for density is d = M/V, where d is density, M is mass, and V is volume.

400

How do you find the radius of a sphere with an equation?

(x−h)2+(y−k)2+(z−l)2=r2

400

formula for circumference angles

 Multiply the radius by pi, a constant that is equal to approximately 3.14. Multiply the result by 2

500

what is the surface area of a square.

Area A = s x s where s is the length of each side of the square.

500

what is the area and volume of a sphere

D = 2 r. Surface Area of a Sphere. A = 4 π r2. Volume of a Sphere. V = (4 ⁄ 3) π r3.

500

how do you find density with only mass

  1. Measure the object's mass (or weight) in kilograms.
  2. Measure the volume of the object in m³.
  3. Divide the mass by the volume.
500

Why is sphere volume formula?

If we observe a sphere, we can see that the height is equal to the sphere's diameter.

solve for circumference of a circle

c=2 pi r
