Pemdas lol, and just search the answer if you don’t get an answer soon
Radius= 1/2 diameter
Radius= 1/2(30)
Radius= 30/2
Radius= 15 feet
Circumference= 2πr
C= 2(3.14)(15)
C= (6.28)(15)
C= 94.2 feet
ANSWER: Radius is 15 feet; Circumference is 94.2 feet
Hope this helps! :)

The average rate of change is:

Step-by-step explanation:
The rational function given to us is;





The average rate of change of this function from x=0 to x=8 is the slope of the secant line connecting:
(0,f(0)) and (8,f(8))
Average rate of change =


Answer:
2.871*10^9
Step-by-step explanation:
add a decimal point at the end of the number ( 2,871,000,000.) then count how many places it takes to move the decimal point between the first and second number (2.8) then write the rest of the numbers higher than "0" after, giving you the 2.871
to show that the number written is in scientific notation you add 10 to the power of the amount of times you moved the decimal place. In this case, because the decimal point was moved a total of 9 times, it would be 10 to the 9th power (10^9).
Answer:
1 option or last option are the best choices sorry if I'm wrong.
