Surface area of a sphere = 4*pi*radius2 radius = diameter/2
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
Surface area of a sphere in square units = 4*pi*radius^2
Surface area of the sphere: 4*pi*2 squared = 50.265 square inches to 3 decimal places
First divide the diameter by 2 to give the radius and use the formula:- Surface area of a sphere = 4*pi*radius2 measured in square units
Surface area of a sphere = 4*pi*(diameter/2)^squared
Surface area of a sphere = 4*pi*radius2 radius = diameter/2
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
Surface area of sphere: 4*pi*15^2 = 900*pi square cm
Surface area of a sphere in square units = 4*pi*radius^2
Surface area of the sphere: 4*pi*2 squared = 50.265 square inches to 3 decimal places
First divide the diameter by 2 to give the radius and use the formula:- Surface area of a sphere = 4*pi*radius2 measured in square units
Oh, dude, you're hitting me with some math here. So, the formula for the surface area of a sphere is 4πr², where r is the radius. Since the diameter is 18 cm, the radius is half of that, which is 9 cm. Plug that into the formula, and you get a surface area of 1017π cm². But like, who's really gonna measure that in real life, am I right?
The surface area of a skittle can be calculated by finding the surface area of a sphere with the same diameter as the skittle. The formula for the surface area of a sphere is 4πr^2, where r is the radius of the sphere. Since the skittle is not a perfect sphere, the surface area may vary slightly depending on its exact shape and dimensions. However, for a standard skittle, the approximate surface area can be estimated using this formula.
By axis if you mean its diameter then surface area: 4*pi*8^2 = 256*pi square units
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!
-- Take 1/2 of the diameter. That's the 'radius' of the sphere. -- 'Square' the radius. (Multiply it by itself.) -- Multiply the result by 4 pi. You now have the surface area of the sphere. P.S.: There really isn't anything else to know about a sphere other than its diameter.
