Answer: 7.5²π square centimeters. OR 56.25π cm²

Step-by-step explanation:

Circumference = diameter × π

So the diameter is 15 cm

Area = πr²

Radius is half the diameter, so 15/2 or 7.5

Area = (15/2)²π cm²

The price of a pair of jeans is $25. If there is a 15% discount, what is the sale price of the jeans?

dusya [7]

Answer:

$29.41

Step-by-step explanation:

You know the discount price is 25 and the original is unknown so call it x. The sale is 15% off and that means that the jeans are 85% of what they used to be since 100-15 is 85. Then you plug it into a formula of 25/x = 85/100 then you cross multiply to get 2500=85x and when you solve for x and round you get $29.41
