The square root of 20 is an irrational number that can be expressed as 2 times square root of 5
10.49
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.
The square root of 1.425 is approximately 1.194. This value can be found using a calculator or by estimating between known squares. In decimal form, it is often rounded to three decimal places as 1.194.
plug it into a calculator - (square root symbol, insert value of volume, end parenthesis)/(height value, pi symbol)
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).
The square root of 13.5 is approximately 3.6742. This value can be calculated using a calculator or by using numerical methods such as the Newton-Raphson method. The square root of a number is a value that, when multiplied by itself, gives the original number.

6*sqrt(3) cannot be simplified. You can find its value using a calculator: it is 10.4 approx.
To calculate the present value of 100 pounds in 1973, you would need to adjust for inflation. Using an inflation calculator, the approximate present value of 100 pounds from 1973 would be around 1,170 pounds in 2021.
