<u>Answer:</u>

cos B = 0.4706

<u>Step-by-step explanation:</u>

The cosine of an angle in a right-angled triangle is the ratio of its adjacent side and the hypotenuse, so:

$cos B = \frac{adjacent}{hypotenuse}\\\\cos B = \frac{8}{17} \\\\cos B = 0.4706$

A sphere has a volume of 457.3 in^3. What is the radius of the sphere?

Ne4ueva [31]

Answer:

$\large\boxed{R\approx4.78\ in}$

Step-by-step explanation:

The formula of a volume of a sphere:

$V=\dfrac{4}{3}\pi R^3$

R - radius

We have the volume V = 457.3 in³. Substitute:

$\dfrac{4}{3}\pi R^3=457.3\qquad\text{multiply both sides by 3}\\\\4\pi R^3=1371.9\qquad\text{divide both sides by 4}\\\\\pi R^3=342.975\qquad\text{divide both sides by}\ \pi\\\\R^3=\dfrac{342.975}{\pi}\qquad/\pi\approx3.14/\\\\R^3\approx\dfrac{342.975}{3.14}\\\\R^3\approx109.2277\to R\approx\sqrt{109.2277}\\\\R\approx4.78\ in$
