A sphere has a radius of 3x+2. Which polynomial in standard form best describes the total surface area of the sphere?

6 answers

you should know the formula for the area of a circle
just plug in 3x+2 for r and look at your choices (which you did not give us)

I must ask Reiny, why must they give us the answer? From my understanding this site is merely to help people acquire the answer by giving the helpful hints about how to solve the problem, not provide it to them.

i really don't know

PLease tell
