Answer:
a=19.6 inches^2
Step-by-step explanation:
The area of a circle can be found using
a=πr^2
We know the radius is 2.5, so we can substitute it in for r
We can also substitute 3.14 in for π
a=(3.14)*(2.5^2)
a=(3.14)*(6.25)
a=19.625
Round to the nearest tenth
a=19.6 inches^2

We know that a department store gives 20 % off the portion of the bill that is over 100 dollars.
Total bill is 250 and x is the amount of money she would have spent without the promotion.
The cost to which the discount applies is 0.8 ( x - 100 ).
<em>Finally the equation we get is 100 + 0.8 (x - 100) = 250.</em>
