Find the ratio of the volume of one sphere to the volume of the right cylinder

yarga [219]

Answer:

Step-by-step explanation:

Let $r$ be the radius of one sphere.

Volume of sphere is $V=\frac{4}{3}\pi r^3$

Since radius is r, the height of the cylinder will be $4r$

Also, the cylinder has the same radius as the sphere: $r$

Volume of Cylinder is $V=\pi r^2 h$

Plugging in the values we get: $V=\pi (r)^{2}(4r)=4\pi r^3$

Ratio of volume of 1 sphere to volume of cylinder is:

$\frac{\frac{4}{3}\pi r^3}{4\pi r^3}=\frac{\frac{4}{3}}{4}=\frac{4}{3}*\frac{1}{4}=\frac{1}{3}$

The ratio is 1:3

Answer choice B is right.

Answer:

x = 17°

Step-by-step explanation:

Angles And Parallel Lines

If two parallel lines are crossed by a third line, corresponding angles are congruent. Also, consecutive angles are supplementary

We can clearly see in the image provided, being w and b parallel, that the corresponding angles (4x-3) and 65° are congruent. We can express that relation as

$4x-3=65$

Operating

$4x=65+3=68$

$x=\frac{68}{4}=17$

So the value of the angle x is 17°
