The surface area of a sphere with a radius of 7cm is about 615.8cm2
The surface area is 804.25 cm2
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.
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.
Surface area = 4*pi*72 = 615.752 square cm to 3 decimal places
The answer is 36π or approximately 113.1 cm.
The surface area of a sphere if its diameter is 9.65 cm equals 292.6cm2
The surface area of a sphere with a radius of 7cm is about 615.8cm2
The surface area of a sphere with a diameter of 7cm is 153.9cm2
18 CM
Surface area of sphere: 4*pi*7^2 = 196*pi square cm
314.28571 cm.
Surface area of a sphere (the golfball) = 4*pi*radius2 square cm
The surface area is 804.25 cm2
Surface area = 4*pi*142 = 784pi square cm
Surface Area = 4*pi*r2 = 6566.9 sq cm
Surface area = 4*pi*32 = 36pi square cm
