How does pi x r2 is used to find th formula for the volume of a half sphere?
Pinkyanna
(pi)R2 is the formula for the area of a circle. It won't help you find the volume
of 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 ?

What is the formula for radius of sphere?
The radius of a sphere is equal to one-half the diameter. If the volume of the sphere is known, then the radius (r) is equal to the cube root of 3/4 of (Volume/pi).
What is the volume of a sphere with a diameter of 15 cm?
First, calculate the radius. It is half the diameter. Then, to calculate the volume, use the formula: Volume = 4/3 x pi x radius3. Pi is approximately 3.1416.
What is half a sphere shape called?
half-sphere hemisphere
What is the formula for the volume of a triangular prism?
The general way to find the volume for any shape is the formulaV=Bh (volume equals base times height). The specific formula used to find the volume of a triangular prism is V=1/2(or 0.5)bhh (volume equals one half or 0.5 times base times height times height again.
If you cut a sphere in half what shape do you get?
You get a hemisphere.
Formula for half a sphere for volume?
Find the volume for the whole sphere (4/3 x pi x radius cubed) then divide by two.
How do you find the volume on a half-sphere?
Calculate the volume of a full sphere, then divide that by 2.
What is the formula for the volume of half a sphere?
4/6 x pi x r3
What is the formula for radius of sphere?
The radius of a sphere is equal to one-half the diameter. If the volume of the sphere is known, then the radius (r) is equal to the cube root of 3/4 of (Volume/pi).
How do you find the volume on a half sphere?
The volume of a sphere is 4/3 x pi x r3 Half of that is 2/3 x pi x r3
What is the volume of half a sphere with a diameter of 12 inches.?
You need to follow these steps:1) Divide the diameter by 2, to get the radius. 2) Use this radius in the standard formula for the volume of a sphere. 3) Divide this result by 2, to get half a sphere.
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!
How do you find the empty space if you put a sphere in a cube?
To determine empty space, we will assume that the sphere fits snugly(so that each side of the cube is touching the sphere). First, we take the volume of the cube, which is just one of its side lengths cubed(side length X side length X side length). Record this quantity. Then we find the volume of the sphere. The formula for the volume of a shere is (4/3) Pi r cubed. Since the sphere fits snugly, we know that the radius is half of the side length. We then take the cube volume and subtract the sphere volume, and that is the empty space remaining.
What is half the volume of a sphere that has a diameter of 6?
The formula for the volume of the sphere is:v= volumer= radiusTo find the radius, you divide the diameter by 2 since the diameter is twice the radius.6/2 = 3 = radiusThen you just plug it in the formulaV= 4/3 pi 33V= 4/3 pi 9V= 12 piV= 37.6991118Now, to find half the volume, you need to divide 37.6991118 by 2 which gives you 18.8495559
What is the volume of a half-sphere if the radius is ten?
Volume of half a sphere = 2/3*pi*radius3 Volume = 2/38pi*103 = 2094.395102 cubic units
Formula to find radius of a sphere?
Depends on the information that you DO have. Half the diameter is the easiest formula, but that only works if you know the diameter.
If the sphere shown has a diameter of 30 units what is the volume of half of the sphere?
Volume of half sphere: (4/3*pi*15^3)/2 = 2250*pi cubic units
