You are building a sand castle and want to use a bucket that holds a volume of 885 in.cubed and has height 11.7 in. What is the radius of the​ bucket? Use 3.14 for π.

Answer:

[tex]4.91 in[/tex]

Step-by-step explanation:

a bucket has the form of a cylinder, which has the following formula for its volume:

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

where r is the radius and h is the height.

Since we need to find the radius, we solve for r:

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

and since we know according to the problem that:

[tex]V=885in^3[/tex]

and

[tex]h=11.7in[/tex]

substituing these values:

[tex]r=\sqrt{\frac{885in^3}{(3.14)(11.7in)}}\\ \\r=\sqrt{\frac{885in^3}{36.738in}}\\\\r=\sqrt{24.0895in^2}\\\\r=4.908in[/tex]

the radius is: [tex]4.908in[/tex] which can be rounded to [tex]4.91 in[/tex]
