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.
How do you find the surface area of a sphere when its volume is 523.5987756 cubic cm?
Use the formula for volume to solve for the radius of the sphere and then plug that radius into the formula for the surface area of a sphere.

What can you do To find a sphere's surface area?
Use this formula: 4 x pi x radius2
How do you find the surface area of a hemisphere?
The surface area of a sphere is 4 π r2. Since a hemisphere is half of a sphere, the equation will be 2 π 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
Where do you use pi in measurement?
circular calculations. circumference, area of circle, vol of sphere, surface area of sphere, etc.
How do you calculate the surface area of a globe?
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...
What is the surface area of a sphere if the radius is 2?
Use the formula: area = 4 pi radius2.
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!
To find a sphere's volume you could use V equals 4πr2?
No, because the volume of a sphere = 4/3*pi*radius3 in cubic units But the surface area of a sphere = 4*pi*radius2 in square units
