A sphere and a right cylinder have the same radius and volume. Find the radius r in terms of the height H of the cylinder
VladimirAG [237]
Volume of cylinder = πR².H

Volume Sphere: =4/3πR³

Volume of cylinder = Volume Sphere (given), then:

πR².H = 4/3πR³

Simplify==> R².H = (4/3)R³==>  H = (4/3)R===> R=3H/4

Plz hurry and answer this correctly!!!
In-s [12.5K]

Answer:

\large\boxed{C)\ \dfrac{8}{5}\pi\ cm}

Step-by-step explanation:

The formula of an area of a circle:

A_O=\pi r^2

The formula of a perimeter of a circle:

P_O=2\pi r

r - radius

We have the area of a circle

A_O=\dfrac{16}{25}\pi\ cm^2

Substitute:

\pi r^2=\dfrac{16}{25}\pi     <em>divdie both sides by π</em>

r^2=\dfrac{16}{25}\to r=\sqrt{\dfrac{16}{25}}\\\\r=\dfrac{\sqrt{16}}{\sqrt{25}}\\\\r=\dfrac{4}{5}\ cm

Calculate the perimeter:

P_O=2\pi\left(\dfrac{4}{5}\right)=\dfrac{8}{5}\pi
