21 is not a perfect square, and none of its factors (1, 3, 7, 21) are perfect squares either, so √21 is already simplified. The easiest way to compute an approximate value is using a calculator; if you are familiar with calculus, Newton's method works to find an approximation manually. Either way, it is approximately equal to 4.58258.
plug it into a calculator - (square root symbol, insert value of volume, end parenthesis)/(height value, pi symbol)
The approximate value of something is an estimate.
The equation for the area of a circle = pi x radius². First square your radius (multiply it by itself) Then multiply it by pi, which you may use either by using the pi button on your calculator or by using an approximate value of 3.1416 (3.14 will be close).
