To calculate the area of a rectangle, you multiply the length times the width. To calculate the area of a square, you multiply one side times another side. To calculate the area of a circle, you multiply the diameter times pi (that's 3.1416). To calculate the area of a triangle, you multiply the height times the base, and divide by 2.
What else can I help you with?
What can change the surface area to volume ratio?
Yes. There are ways to do that, but it depends on what you wish to change the surface area of. Changing the surface area of something like, say, a shotput is difficult, but changing the surface area of a balloon can be accomplished by merely blowing it up (more) or deflating it.
Why does crushing help a solid solute dissolve?
The rate of dissolution of a solid is dependent on the surface area reaction. By crushing the cube, the surface area is greatly increased, thus increasing the rate of dissolution.
How does a large surface area help the function of a system?
A surface is where things happen between what is on one side of the surface and the other. Thus in general if you want more of these happenings (eg gas exchange) you need the biggest possible surface area. If however you want to minimise these happenings (eg heat loss) you try and reduce the surface area.
What is the unit of measure in finding the area?
The surface area is measured in square units
Why fins are provided on heat transferring surfaces?
Using fins increases the surface area of the cover plate and more is the surface area meaning more place for heat dissipation or heat exchange. In simple words it multiplies the cooling effect.
What is the equation for the surface area of a sphere?
Surface area of a sphere with radius r = 4(pi)r2
Formula for area of a sphere?
There is NO equation for the area of a sphere Assuming you mean surface area, the surface area of a sphere of radius r is 4πr^2.
Where might one find the mathematical equation for the surface area of a sphere?
One might find the mathematical equation for the surface area of a sphere in a mathematics textbook. One might also find the equation at online math study groups.
Equation for surface area of a sphere?
4 pi r 2
What is the equation Area length X width used for?
the equations tell you what the surface area of somthing is
What is the equation area equals length multiplied by width used for?
The answer is in the question "area = length multiplied by width" the equation tells you what the surface area of something (eg a football pitch) is.
What is the equation for the total surface area of a pyramid?
s+s+s+s+b=area of pyramid
How do you find the surface area of a cylinder if you only have the height and volume?
use algebra to find the radius, then plug the height and radius into the surface area equation
What is the radius of a sphere that has a surface area of 1742400 squre ft?
Finding the radius of a Sphere by using the surface area is a multi-step mathematical equation. The radius (r) of a sphere with a surface area of 1742400ft is 372.365ft.
How do I find the radius of a cylinder with the height and the surface area?
Surface Area = pi*r*(r + h) When you substitute for pi and h you will get a quadratic equation in r.
What is the relation between pressure and surface area?
Pressure is inversely proportional to surface area. This means that as surface area decreases, pressure increases and vice versa, given a constant force. This relationship is described by the equation: Pressure = Force / Area.
What is the equation to calculate water depth?
The equation to calculate water depth is: [ Water Depth = Volume of Water / Surface Area of Water ]
