It takes 4.5 ounces of copper to make a copper pipe fitting. American Pipe estimates they produce an average of 25.4 fittings per week. How much copper will it take to make fittings for the whole year?

256π units²   (answer b)

step-by-step explanation:

the formula for the surface area of a sphere of radius r

is             a = 4πr²

and so, if r = 8 units, then the surface area is:

a = 4π(8 units)² = 256π units²   (answer b)

answer: ok

step-by-step explanation:

the ratio would be 4: 3, the four being for jackson, and the three being not for him.
