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
If the diameter of a sphere is doubled, its surface area increases by a factor of four. This is because the surface area of a sphere is calculated using the formula (4\pi r^2), where (r) is the radius. When the diameter is doubled, the radius also doubles, leading to a new surface area of (4\pi (2r)^2 = 16\pi r^2), which is four times the original surface area.
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
Surface area of a sphere = 4*pi*radius2 radius = diameter/2
Surface area of a sphere = 4*pi*(diameter/2)^squared
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
If the diameter of a sphere is doubled, its surface area increases by a factor of four. This is because the surface area of a sphere is calculated using the formula (4\pi r^2), where (r) is the radius. When the diameter is doubled, the radius also doubles, leading to a new surface area of (4\pi (2r)^2 = 16\pi r^2), which is four times the original surface area.
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
The formula for the surface area of a sphere is 4πr^2, where r is the radius of the sphere. Since the diameter is 18 cm, the radius would be half of that, which is 9 cm. Plugging this into the formula, we get 4π(9)^2 = 4π(81) = 324π cm^2. Therefore, the surface area of the sphere is 324π square centimeters.
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
The formula for the surface area of a sphere is 4πr^2, where r is the radius of the sphere. Since the diameter is 18 cm, the radius is half of that, which is 9 cm. Plugging this into the formula, the surface area of the sphere is 4π(9)^2 = 324π square cm.
