How do you find the surface area of a net?
How do you find the suface area of a net? Answer: Do the formula for each shape that is in the net.
How do you find a sphere's suface area?
4(pi)r^2 (4 * pi * r^2)
What is the formula to find surface area of a sphere?
Surface area = 4*Pi*radius2
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!
What is the formula to find the surface area of the moon?
Assuming the moon to be a sphere, the formula to find its surface area is 4/3*pi*r^3 where r is the radius of the moon.

How do you find a sphere's suface area?
4(pi)r^2 (4 * pi * r^2)
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 is the formula to find the suface area of a cube?
Just add the area of the six squares - that gives you 6a2, where a is the length of one side.
What is the formula to find surface area of a sphere?
Surface area = 4*Pi*radius2

What is the formula to find the surface area of the moon?
Assuming the moon to be a sphere, the formula to find its surface area is 4/3*pi*r^3 where r is the radius of the moon.
What can you do To find a sphere's surface area?
Use this formula: 4 x pi x radius2
Total surface area of a sphere with a radius of 4?
To find the surface area of a sphere, the formula is: 4pi*r2So plug in numbers: 4pi(4)24pi(16)=64pi
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 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 ?
Suppose the sphere below with radius r has a surface area equal to 45 units 2 Find the surface area of the sphere with twice the radius'?
The area of a sphere is given by the formula A = 4πr² A sphere with radius r has an area = 4πr² A sphere with radius 2r has an area = 4π(2r)² = 4π.4r² = 16πr² The ratio of the larger sphere to the smaller = 16πr² : 4πr² = 4 : 1 If the area of the smaller sphere is 45 units then the area of the larger sphere is 45 x 4 = 180 units.
