HELP ASAP!!! the formula for the volume of a cylinder is v = πr2h, where v is the volume, r is the radius, and h is the height. solve the formula for r, and then use it to answer the question. a cylindrical bucket contains 314 cubic inches of water. the height of the water is 4 inches. what is the radius of the bucket, to the nearest whole number? use 3.14 for π.

Answer :

SOLUTION:

[tex]V=\pi r^2h[/tex]

We want to make r the subject of the formula here,

[tex]\begin{gathered} r^2=\frac{V}{\pi h} \\ \\ r=\sqrt{\frac{V}{\pi h}} \end{gathered}[/tex]

From the question,

V = 314 cubic inches, h = 4 inches.

We find the radius to be;

[tex]\begin{gathered} r=\sqrt{\frac{314}{4\times3.14}} \\ \\ \\ r=\sqrt{25} \\ \\ r=5 \end{gathered}[/tex]

Thus, the radius of the bucket is 5 inches
