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

yarga [219]

Answer:

Step-by-step explanation:

<em>Let $r$ be the radius of one sphere.</em>

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: $V=\pi (r)^{2}(4r)=4\pi r^3$

<u>Ratio of volume of 1 sphere to volume of cylinder is</u>:

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

The ratio is 1:3

Answer choice B is right.

A woman is walking at the rate of 90 yards per minute. How fast is she going in feet per second?

motikmotik

Answer:

She is going at the rate of 4.5 feet per second.

Step-by-step explanation:

Given:

The rate of walking is 90 yards per minute.

Now, to find the rate in feet per second.

1 yard = 3 foot.

1 minute = 60 seconds.

So, first we find the rate of walking per second in yard = $90\div 60$

Therefore by dividing we get = $1.5 yard$

Now, we find the rate of walking per second in feet = $1.5\times 3$

So, by multiplying we get = $4.5 feet$

Therefore, she is going at the rate of 4.5 feet per second.
