-20 in simplest radical form

2√5

Step-by-step explanation:

Here is how to do that! First we write the square root of 20 like this:

√20

The largest perfect square of the factors of 20 is 4. We can therefore convert √20 like this:

√4 × 5

Next, we separate the numbers inside the √ as such:

√4 × √5

√4 is a perfect square that equals 2. We can therefore put 2 outside the radical and get the final answer to square root of 20 in simplest radical form as follows:

2√5

step-by-step explanation:

there is a formula i can give you:

it is r^2*n*sin(360/n) divided by 2 where r represents the "radius" and n is the number of sides.

plug them in:

(10sqrt(3))^2*6*sin(360/6) divided by 2

100*3*6*sin(60) divided by 2

900*sin(60)

900*sqrt(3)/2

450*sqrt(3)

approx is 779.4 cm^2
