Use the formula to find the area of a circle: Area = pi times radius squared
Divide each diameter by 2 to get the radius
Ex) 50/2=25
A= pi times 25 squared
25^2=625
A= 625 times pi
A=2,587.5
Answer:
3
Step-by-step explanation:
63/21 = 3
Solution = m(x)=-(x-7)^2+49
First find 10%
so 17.64/2
= 8.82
then move decimal over one
so $88.2
is the bill
