Remember......when we have this situation (a/b)^(-m).....where a/b ≠ 0...we can  "flip"  the fraction and make the expononent positive.....so......

(3/4)^(-2)   =     (4/3)^2  =   (16/9)

(x^4 - 2x^2y - 3y^2)  / (x^2 - 6x^2y + 5y^2)  =

[(x^2 - 3y) (x^2 + y)] / [(x^2 - 5y) (x^2 - y) ]   .....this is as much as we can do......no factors "cancel"

Radix has assumed that this is a cylinder......it could also be a cone.....if so....the height (in cm) is .....

$${\mathtt{52}} = \left({\frac{{\mathtt{1}}}{{\mathtt{3}}}}\right){\mathtt{\,\times\,}}{\mathtt{\pi}}{\mathtt{\,\times\,}}{\mathtt{36}}{\mathtt{\,\times\,}}{\mathtt{h}} \Rightarrow {\mathtt{h}} = {\frac{{\mathtt{13}}}{\left({\mathtt{3}}{\mathtt{\,\times\,}}{\mathtt{\pi}}\right)}} \Rightarrow {\mathtt{h}} = {\mathtt{1.379\: \!342\: \!840\: \!129\: \!759\: \!6}}$$  

 8 ounces  = 1 cup      so......176 ounces =  22 cups

So  .....22cups / 32 people =    11/16 cup per person

The total length is    16 x (6 + 3/4)   =  96 + 12   = 108  meters

So   108/20   =   54/10   = 5.4 meters each

945 + 254 =  1199......   before the sale.....

1199 - 245 =  954 sold

√2*√6 *√110 *√165  =

√12 *√[11*5*2]* √ [11*5*3] =

√[4*3] *√[11*11] *√[5*5] * √[3*2] =

2√3 * 11 * 5 * √[3 *2]  =

2√[3*3] * 11 * 5 *√2   =

2* 3 * 11 * 5* √2 =      6 * 55 * √2 =   330√2

Just multiply 5 times 12715.......and then...... move the decimal point to the left four places in your answer
