The interior angles formed by the side of a hexagon have measures of them up to 720° what is the measure of angle a

timofeeve [1]

Answer:

n = 6

Step-by-step explanation:

the formula for interior angle is ( n-2)

but we given the measure of one angle, so solve

720 = (n - 2)180

720/180 = (n - 2)

4 = (n - 2)

combine the like terms

4 + 2 =n

6 = n

Solve the equation x = 5/3 (pie) (r^3) for r.

DENIUS [597]

Answer and Step-by-step explanation:

To solve for r, we need to get everything away from r. We can start off by moving five thirds, and pi.

$x = \frac{5}{3} \pi r^{3}$

Multiply each side by $\frac{3}{5}$ , then divide by $\pi$ (pi)

$\frac{3x}{5\pi } = r^{3}$

Now, take the cubed root of both sides.

$\sqrt[3]{\frac{3x}{5\pi } } = r$

^^ That is the answer.
