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!
Formula for surface area of a spherical dome?
The surface area of a sphere is 4(3.14)R2where R is the radius of the sphere so the surface area of your dome is half of that. 2(314)R2
What is the formula for the suface area of a sphere?
Surface area of a sphere = 4πr2
Formula for surface area of a sphere?
The formula for the surface area of a sphere is: 4 pi r 2
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.
What is the answer for the hemisphere?
The answer for the hemisphere is half the volume of a sphere, which is given by the formula (2/3)πr³, where r is the radius. The surface area of a hemisphere is half the surface area of a sphere, given by the formula 2πr².

How does pi x r2 is used to find th formula for the volume of a half sphere?
(pi)R2 is the formula for the area of a circle. It won't help you find the volumeof a half sphere, at least not without some calculus.What you need is the formula for the volume of a sphere: V = 4/3 pi R3 .Do I have to explain that the volume of a half sphere is just half of that ?
Formula for calculating the area of sphere?
The formula for calculating the surface area of a sphere is 4πr², where r is the radius of the sphere. This formula represents the area covered by the curved surface of the sphere.
Formula for surface area of a spherical dome?
The surface area of a sphere is 4(3.14)R2where R is the radius of the sphere so the surface area of your dome is half of that. 2(314)R2
What is the formula for the suface area of a sphere?
Surface area of a sphere = 4πr2
Formula for surface area of a sphere?
The formula for the surface area of a sphere is: 4 pi r 2
How do you get the formula of the area of the sphere?
Surface area of a sphere = 4*pi*radius2
Suppose a rounded ball is cut into two equal pieces then what would be the formula to find the area of one-half piece of this ball?
Surface area of a sphere (a rounded ball) = 4*pi*radius2 Surface area of half a sphere = 2*pi*radius2
What is the surface area of a sphere?
The formula for the surface area of a sphere is 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.
What is the surface area of a sphere with diameter 18 CM?
Oh, dude, you just need to find the radius first, which is half of the diameter, so that's 9 cm. Then you use the formula for the surface area of a sphere, which is 4πr^2. Plug in 9 for r, square it, multiply by 4, and then multiply by π. That gives you a surface area of 1017π square cm, or about 3190 square cm. Easy peasy!
