Some common examples from various sciences:
Biology (much cellular activity takes place at, or is affected by, the cell's surface),
Chemistry (many reactions depend on surface areas, particularly for catalysts),
Physics (evaporation, radiation and absorption of heat, incident light; friction)
Find the surface area of a cylinder with a radius of 16 and a height of 23. Use 3.14 for π. Round your answer to the nearest te
Alex wants to know how much gift wrap to use to wrap a box. Is that surface,area, volume
actually surface area is always of 3 -d figures not for 2 d figures. area of rectangle= length x breadth.. remember never use surface area term for 2d figures. :)
The surface area of a box, which is a cuboid, depends on its length, width and height. A cube is a special type of cuboid in which the length , width and height are all the same.
To calculate the surface area of a sphere use the formula - 4pr2 r being the radius of the sphere. and 'p' being pi 3.14...
To do this question, we have to ask ourself, what formula do you use to find the surface area of a sphere. The answer should be known to you, but it is 4πr2. Since we know how to find the surface area for a full sphere, then finding the surface for a half sphere is just half the job. You use the formula for the full sphere 4πr2, and divide it by 2... so (4πr2) / 2 . Voila!
use area
Surface area of a sphere = 4*pi*radius squared
Well, first of all, that's no sphere.-- A sphere with surface area = 300 has volume = 488.6.-- A sphere needs surface area of 304.6 in order to have volume = 500.But this is just a ratio exercise, not a geometry problem, so we'll just use the numbersgiven in the question. It's just some sort of wacky humongous paramecium:Surface area = 300Volume = 500Ratio of (surface area)/(volume) = 300/500 = 0.6 .
What is the surface area of this cone? Use π ≈ 3.14, and round your answer to the nearest hundredth. 8 in 4 in square inches
A good Latex paint, or satin finish paint will offer a smooth, and easy to clean surface...granted the surface is within a living area of your home. A basement area needs to be waterproofed before hand.
math you silly goose
You divide the diameter by 2, to get the radius. Then you use the formula for the surface area of a sphere. Surface area of a sphere = 4*pi*radius^2
Use this formula (Ï€ = Pi): Surface area = 4Ï€r2
First of all, you can't use 'kilometers' to measure surface area. If you're metric and you want surface area, you have to use 'square kiliometers'. They're different.The Philippines cover 316,294 of those.That's the same area as 122,121 square miles.
Yes, every job needs math.
