Volume = 4/3*3.41*33 = 122.76 cubic cm
The approximate surface area of a sphere with a diameter of 15 centimeters is 707cm2
The surface area, to the nearest tenth, of a sphere that has a diameter of 14 inches is: 615.8 inches2
The volume of a sphere whose diameter is 25 centimeters is 8,181 cubic centimeters
SA = 265.9 in2
-- 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.
725.466
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 is 3217cm2
The radius of a sphere with antipodes 8 cm apart is 4 cm. The distance between the antipodes of a sphere is the diameter of the sphere. The radius is half the length of the diameter.
Volume = 606.1 cm3
The volume (to the nearest cubic meter) is 87m3
Surface area of the sphere = 4*pi*92 = 1017.87602 or about 1018 sq cm
The idea is that in both cases, you replace the radius in the formula: V = (4/3) x pi x radius cubed ... and do the calculations. The radius is half the diameter.
Use the formula for a sphere. First divide the diameter by 2; that will give you the radius.
