Answer:
131.7
Step-by-step explanation:
So the original price is 40 dollars. We can see how much she saved by multiplying the original amount with the discount. 40 x .60=24. So she saved 24 dollars. We can then subtract 24 from 40 to get a price of 16 dollars.
First one:
The circumference of the whole circle is (2π x the radius),
and 60° is (60/360) = 1/6 of the whole circumference.
Second one:
The area of the whole circle is (π x the radius²), and
the 40° sector is (40/360) = 1/9 of the whole area.
I hope this is enough help.
