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 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 sphere with a diameter of 8 inches is 201.1 inches2
The surface area of a sphere with a diameter of 18 feet is: 1,020 square feet.
The approximate surface area of a sphere with a diameter of 15 centimeters is 707cm2
Approximately 50.265 square inches.
The surface area, to the nearest tenth, of a sphere that has a diameter of 14 inches is: 615.8 inches2
The surface area of this sphere is 2,827 square feet.
The surface area is 1,020 square feet.
201.06 inches2
Surface area of a sphere in square units = 4*pi*radius^2
The surface area of a sphere with a diameter of 7cm is 153.9cm2
Approximately 50.265 square inches.
The surface area of a sphere if its diameter is 9.65 cm equals 292.6cm2
The surface area of a sphere with a diameter of 8 inches is 201.1 inches2
Surface area of a sphere = 4*pi*(diameter/2)^squared
Surface area of a sphere = 4*pi*radius2 radius = diameter/2
The surface area of a sphere with a diameter of 10 is about 314.16 units2
Surface area of a sphere = 4*pi*radius2 Surface area = 16*pi = 50.26548246 or 50 square inches.
