Answer:
around 153.94
Step-by-step explanation:
The formula is pi * radius squared
so pi * 7^2 is
pi * 49 = around 153.94
Answer:
y equals mx plus b?
Step-by-step explanation:
idk
OK the next step is to multiply 3r -1 by -7r
this gives us -21r^2 + 7r and we write it below -21r^2 + 25r
and subtract
This gives us 18r and we bring down the -6 to give
18r - 6
Finally we divide 18r by -3r to give -6 then add - 6 to the r^2 - 7r on the top
then multiply -3r - 1 by -6 to give 18r - 6
subtraction then leaves nothing.
so the answer is r^2 - 7r - 6
48, 53, 58, 63 is from low to hight numbers
