I suspect 4/2 should actually be 4/3, since 4/2 = 2, while 4/3 would make V the volume of a sphere with radius r. But I'll stick with what's given:
In Mathematica, you can check this result via
D[4/2*Pi*r^3, r]
Well if it is a number like .933333333 you will have to round it, So now it is .93 and .93 in a fraction is 93/100
If we know that Laura's canvas is square, and one side is 22cm,
area of a square is l*w, with a special case of l=w
the area will be
A= l*w=22*22=484cm^2
also, Asquare is=l^2
If wholesale cost is x, then retail is x plus the percentage change in x. (1 + .34)x = 1.34x.
1) surface area = 18m^2 * pi * 26m = <span>8424pi m^2</span>
