A=2xy+2xz+2yz

a=2(xy+xz+yz)

a=2(5.5*3.4+5.5*8.25+3.4*8.25)

a=2(18.7+45.375+28.05)

a=2(92.125)

a=184.25 cm^2

Option B

Step-by-step explanation:

The formula of the volume of a cylinder is:

V=\pi r^2h

Where the radius is "r" and the height is "h".

The formula of the volume of a rectangular prism is:

V=Ah

Where "A" is the area of the base and "h" is the heigth.

As both volumes are equal, you can write:

V=V\\\pi r^2h=Ah

Find the area of the base, which is a square, with the formula:

A=s^2

Where "s" is the lenght of any side of the square.

A=(9cm)^2=81cm^2

Divide both sides of the equation by "h" (because the heights are equal) and solve for the radius:

\frac{\pi r^2h}{h}=\frac{Ah}{h}

\pi r^2=81cm^2\\\\r=\sqrt{\frac{81cm^2}{\pi}}

r=5.07cm≈5.1 cm
