with a tape measure
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.
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.
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.
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.
The surface area is measured in square units
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.
Surface area of a sphere with radius r = 4(pi)r2
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.
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.
4 pi r 2
the equations tell you what the surface area of somthing is
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.
s+s+s+s+b=area of pyramid
use algebra to find the radius, then plug the height and radius into the surface area equation
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.
Surface Area = pi*r*(r + h) When you substitute for pi and h you will get a quadratic equation in r.
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.
The equation to calculate water depth is: [ Water Depth = Volume of Water / Surface Area of Water ]
