Find the volume of a sphere with a diameter of 4 feet. (Give your answer correct to 2 decimal places.)

Question

anonymous · Answer

V = (4/3)*pi*(r^3)
V = 33.51 cubic feet

anonymous · Answer

$$v=\frac{4 \pi  r^3}{3} $$When r is 4, v = 268.08

The numerator starts off with 4^4, 256, and pi/3 is close to 1, so 33.51 is too small by a factor of 8tish.

im lost

anonymous · Answer

Sorry.  theawesome's answer is correct.  I used the diameter value 4, as the radius.  The radius is 2.

anonymous · Answer

so the answer is 2

anonymous · Answer

The answer is:$$\frac{4 \pi  2^3}{3}=33.5103 $$
