What Units can you use to find sphere's surface area?
The term units usually refers to a measurement of size, area or volume. These can be expressed in any way you choose. For example, units of measurement can be centimeters, inches, square feet, square meters, cubic yards, etc. Surface area would be expressed in some squared unit like square inches, etc. Characteristics such as length, or area are measured in units. In the case of a sphere, knowing either the diameter or radius is all that's required to determine the surface area.
What is the unit of measure in finding the area?
The surface area is measured in square units
Is square inches a possible unit for surface area?
yes
What Unit of surface area is equal to 2471 acres?
2,471 acres is equal to: 107,636,760 square feet OR 3.86 square miles of 'surface' area.
What unit would measure the surface area in inches?
square inches
Is there any relatoin between radian and steradian?
nopes. radian is the ratio between the length of an arc and its radius. A steradian can be defined as the solid angle subtended at the center of a unit sphere by a unit area on its surface. For a general sphere of radius r, any portion of its surface with area A = r2 subtends one steradian.
Which cubes have the same volume and surface area?
A cube with an edge length of 6 units has a 216 square unit surface area and a 216 cubic unit volume.
Does area measure the number of square unit's that cover an objects surface?
yes
Is the measure of the number of unit squares needed to cover a surface?
Yes, the measure of the number of unit squares needed to cover a surface is referred to as the area of that surface. Area quantifies the extent of a two-dimensional shape and is typically measured in square units, such as square meters or square feet. Thus, counting the unit squares provides a practical way to determine and visualize the total area.
Why in coulomb's law for charges force is inversely proportional to square of distance between charges?
Imagine a light bulb in the center of a sphere. It emits a fixed quantity of light. That's how much light will reach the sphere. The concentration of light per unit of area, on the sphere, will depend upon how large the sphere is. And the area of a sphere is proportional to the square of the radius of the sphere. So the intensity of the light will be inversely proportional to the square of the distance which it has to travel. It is effectively illuminating a larger sphere (even if there is no actual sphere, the principle remains the same).
How do you find the lateral area of a sphere?
there would be no" lateral" surface to a sphere because it is round , only with a cube ,pyramid or rectangular object would you have lateral surface,although it is still possible to determine the surface area and volume of a sphere, the formula to calculate the area of a sphere is 4x pie x radius squared, to calculate the volume the formula is 4x pie x radius cubed divided by 3, to calculate a hemisphere you would divide the answer in half.
Why is area always written in square units?
Area is always reported in square units because a square unit measures the length and width on a square. Square units measure the surface of a square or rectangle.
