Answer:
28.26ft^2
Step-by-step explanation:
The formula for area of circle is:
A=3,14*r^2, where r =3 and 3,14 is pie number, so we have
A=3.14*9=28,26
Percent change formula states that
((New-old)/old) x 100 = the percent change / percent increase
So if we take your equation and plug it into our formula
((225-120)/120) x 100
(105)/120 x 100
.875 x 100
87.5 % increase of students on the trip
Hope this helps!
Answer:
c < 4
Step-by-step explanation:
whenever you divide or multiply an inequality by a negative it is a rule that you must reverse the inequality symbol
so -c > -4 means you must divide or multiply by a negative one to get 'c' by itself; therefore it becomes c < 4
Wrong because you need to add the -2 to the 8.... I hope this helps
The answer would be 59,844 or around that number
