surface area sphere = 4πr² → r = √(surface_area/4π) = √(1296π in²/4π) = √(324 in²) = 18 in Volume sphere = 4/3 πr³ = 4/3 π (18 in)³ = 7776π in³
Volume of a sphere = 4/3*pi*radius3 Volume = 4/3*pi*93 = 3053.628059 Volume = 3054 cubic feet to the nearest cubic foot.
The diameter of a circle is twice the radius. A circle with a radius of 9 would have a diameter of 18. (9*2=18).
the equation to find circumference is C=2*pi*radius so when you have a radius of 18 inches, C=113.097
A circle with a radius of 18 centimeters has an area of 1,017.88 square centimeters.
