Answer:

As Per Provided Information

A cylinder has a volume of 320 pi cubic inches and a height of 5 inches.

We have been asked to determine the radius of the cylinder .

<u>Using </u><u>Formulae </u>

<u>\purple{\boxed {\bf\: Volume_{(Cylinder)} =  \pi {r}^{2}h}}</u>

Substituting the value and let's solve for radius .

\sf \qquad \longrightarrow \: 320  \pi \: =  \pi \:  \times r {}^{2}  \:  \times 5 \\  \\  \\ \sf \qquad \longrightarrow \:320 \cancel{\pi} =  \cancel{ \pi} \times r {}^{2}  \:  \times 5 \\  \\  \\ \sf \qquad \longrightarrow \:320 = r {}^{2}  \:  \times 5 \\  \\  \\ \sf \qquad \longrightarrow \:r {}^{2}  \:  =  \cfrac{320}{5}  \\  \\  \\ \sf \qquad \longrightarrow \: {r}^{2}  =   \cancel\cfrac{320}{5}  \\  \\  \\ \sf \qquad \longrightarrow \: {r}^{2}  = 64 \\  \\  \\ \sf \qquad \longrightarrow \:r \:  =  \sqrt{64}  \\  \\  \\ \sf \qquad \longrightarrow \:r \:  = 8 \: inch

<u>T</u><u>herefore,</u><u> </u>

  • <u>Radius </u><u>of </u><u>cylinder </u><u>is </u><u>8</u><u> </u><u>Inches </u><u>.</u>

Butoxors [25]

Ans

I = sqrt(P/R)

Step-by-step explanation:

You divide both sides by R first

P/R = I^2 R/R

So,

I^2 = P/R

take the square root of both sides

I = sqrt(P/R)
