Randy’s circular garden has a radius of 1.5 feet he wants to enclose the garden with edging that costs $0.75 per foot about how much will the edging cost? Explain.

Respuesta :

circumference = [tex]2 \pi r[/tex]
circumference = [tex]2 \pi (1.5)[/tex]
circumference = 9.42 feet

The circumference is 9.42 feet, so we need to get fencing for 10 feet (assuming the fence comes in feet, i.e. you cant buy half a foot)

1 feet = $.075
10 feet = $0.75 x 10 = $7.50
