Surface area of sphere = 4*pi*122 = 1809.557368 or about 1810 square cm
The surface area of a sphere with a radius of 2 is about 50.27 units2
The formula for calculating the volume of a sphere is 4/3 pi r3. If your sphere has a radius of 3 cm, you can expect it to have a volume of about 113 cubic centimeters.
The volume of a sphere with a radius of 11 cm is: 5,575 cm3
The surface area of the sphere with the radius doubled is 200 units2.---> Confirmed
Surface area of sphere = 4*pi*122 = 1809.557368 or about 1810 square cm
-- You have to ask somebody for the radius of the sphere, in meters. If they tell you the diameter instead, then the radius is 1/2 of the diameter, in meters. -- Multiply (4) times (pi) times (the radius)2 . That's the surface area of the sphere, in square meters. -- Round the answer to the nearest square meter.
The volume of a sphere with a radius of 4cm is about 268cm3
The volume of a sphere with a radius of 2cm is about 33.5cm3
The surface area is 4 pi r 2. Radius is 7.6cm. This gives you 725.47cm2 rounded up in the hundreds
The surface area of a sphere with a radius of 4.75 is about 283.5 units2
The surface area of a sphere with a radius of 13ft is about 2,123.7ft2
The surface area of a sphere with a radius of 2 is about 50.27 units2
No, if the radius of a sphere doubles, its surface area increases by a factor of 4, not simply doubling. The surface area of a sphere is proportional to the square of the radius.
The formula for calculating the volume of a sphere is 4/3 pi r3. If your sphere has a radius of 3 cm, you can expect it to have a volume of about 113 cubic centimeters.
The volume of a sphere with a radius of 11 cm is: 5,575 cm3
The surface area of a sphere with a radius of 5m is 314.2m2
