the circumfrence of a spherical candle is 15.7 inches. What is the volume of wax in the candle?

Question

anonymous · Answer

4pir=15.7
so r =15.7/4pi
volume=4pir^3/3
use this value i=of r to find the volume :)

lol....its a ball of wax

anonymous · Answer

I still am trying to figure out how to solve it!

amistre64 · Answer

find the radius bu cutting it in half; and taking the radius of the circumference of the circle

amistre64 · Answer

2pir = 15.7

r = 15.7/2pi

amistre64 · Answer

umm.... 4pi r = surface area; not circumference if i recall correctly

amistre64 · Answer

then the volume of the wax ball is:

$$\frac{4\pi (\frac{15.7}{2\pi})^3}{3}$$

anonymous · Answer

i don't think there's anything called a cicurmference for a 3d object...i think he meant surface area...

amistre64 · Answer

volume should be abt; 65.35....

amistre64 · Answer

the circumference of a 3d ball is just the measure of the 'great cirlce'

anonymous · Answer

cubed or squared?

amistre64 · Answer

volume is in cubed units

amistre64 · Answer

inches^3
