Simplify= 4r+3
Because 8r plus -4r which is 4r and then 3 can’t be simplified so u keep it the same
Then the answer if r=5 is 23
Because the equation looks like 4(5)+3
5 times 4 is 20 plus 3 is 23
The sector area is = pi * r^2 (circumference/360). Do the work inside the () first and then multiply by pi r^2
The answer it’s D again lol
