Question

Find x. You have to use Pythagorean theorem

Answer 1

x = √18 = 4.24

Explanation:

The radius is half of diameter so radius is 6/2 = 3

Right triangle is formed by 2 equal sides which is the same as radius

According to Pythagorean theorem: x^2 = 3^2 + 3^2

x^2 = 9 + 9 = 18

x = √18 = 4.24
