A spherical snowball melts so that its radius decreases from 6 inches to 5.8 inches. a) Find the exact change in volume of the snowball. b) Find the approximate change in the volume of the snowball.

Question

anonymous · Answer

volume of a sphere is $\frac{2}{3}\pi r^3$ you have to compute 
$$\frac{4}{3}\pi \times 6^3-\frac{4}{3}\pi \times (5.8)^3$$

anonymous · Answer

use a calculator since it says approximate

anonymous · Answer

actually i got that exactly backwards
it says approximate change from 6 to 5.8 so it should be the negative of what i wrote above

anonymous · Answer

how i find the exact change?

anonymous · Answer

Use a calculator for exact.

anonymous · Answer

I used one for the approximate too thought
