Well, they're saying 9 with an exponet of 2 multiplied by something equals 27..... Hmmm.....
Question 1:
Perimeter = 18ft
area = 15ft²
Question 2:
Perimeter = 11m
Area = 7.5m²
It would be log(81) because of the power rule...
First find the area of the circle using A=pi*r^2
pi*36
Then divide this by 4 because the shaded region is 1/4 of the circle
(36*pi)/4=9*pi
Final answer: B
