The area of a circle is 9π ft². What is the circumference, in feet? Express your answer in terms of \piπ. (pi)

6π feet.

Step-by-step explanation:

The area = π r^2 = 9π

So r^2 = 9π/π = 9

r = 3 ft.

So the circumference = 2πr

= 2*π*3

= 6π feet.

answer:   expression= p+p*d%

price reduction + sale price = $625

sale price: $p+$p*d%

where d% is the percentage of discount

step-by-step explanation:

original price = p

price went down by $150 price reduction $p*d%

sale price= $ 475

therefore the price before sale is: $625

and the expression that shows the price before sale is: p+p*d%
