when givin the legs of a right triangle such as 1,2.4 how do u calculate the hypotenuse? also numbers of legs r 4,8 15,26 1.5,2 find the hypotenuse-longest side of the right triangle

prob # 2
the circumference of a circle can be calculated by useing the formula C=2,PI,R where c is the circumference and r is the radius find the circumference of a circle with radius 18 cm.

Use the Pythagorean Theorem to determine the length of a hypotenuse when lengths of both legs are known.

C = 2 * Pi * r

You're told the value of r; it's 18.

Substitute the value 18 for the variable r in the formula for C, and do the math.
