Write sentences into algebraic expressions. the area of a square is the square of its side, s. the volume of a cube is the cube of the length of its side, s. the surface area of a sphere with radius r is four times the product of π and the square of the radius.

The area of a square is the square of its side, s =) a= s²

The volume of a cube is the cube of the length of it's side,s =) v=s³

The surface area of a sphere with radius r is four times the product of π and the square of the radius=) a=4(π X r²)

Hope this is correct and helpful! :-)
