find the volume of a sphere with a radius of 2 feet. express the answer in terms of pie and then round the answer to the nearest whole number.

Question

zepdrix · Answer

Volume of a sphere is given by:$$\Large\bf\sf V\quad=\quad \frac{4}{3}\pi \color{royalblue}{r}^3$$
So let's plug our given value into the expression:$$\Large\bf\sf V\quad=\quad \frac{4}{3}\pi \left(\color{royalblue}{2ft}\right)^3$$

zepdrix · Answer

Then we'll need to simplify.

zepdrix · Answer

Apply the cube to each term in the brackets (cube the units also).

zepdrix · Answer

$$\Large\bf\sf V\quad=\quad \frac{4}{3}\pi\cdot2^3ft^3$$
