A right triangle has legs of lengths 6 and 15 inches. Find the length of the hypotenuse (nearest tenth).

zubka84 [21]

Answer:

The length of the hypotenuse is 16.2 inches.

Step-by-step explanation:

$c^{2} = a^{2} + b^{2}$

$c^{2} = 6^{2} + 15^{2}$

$c^{2} = 36 + 225$

$c^{2} = 261$

$\sqrt{c^{2} } = \sqrt{261}$

$c = 16.2$

What is pi???????????????

Kipish [7]

Answer:

The ratio of a circle's circumference to its diameter

In other words: all the way around a circle divided by all the way across it.

The symbol is π (pi)

No matter how large or small the circle, its circumference is always π times its diameter.

π = 3.14159265358979323846... (the digits go on forever without repeating)

A rough approximation is 22/7 (=3.1428571...), but that is not accurate.
