How do you figure out surface area for half sphere?
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!
Find the surface area of a sphere with a diameter of 78 use 3.14 for pi?
The surface area of a sphere with diameter 78 and using 3.14 for Pi is about 19,103.76 units2
How do you find the surface area of a sphere with a radius of 15 inches?
Use this formula (Ï€ = Pi): Surface area = 4Ï€r2
How do you calculate the surface area of a spherical tank with a diameter of 96 inches?
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
What is the surface area of a sphere if the radius is 2?
Use the formula: area = 4 pi radius2.
