Answer:
70
Step-by-step explanation:
First, put the values they gave you in order from least to greatest.
52 62, 72, 77
In order for the median to be 72, it has to be in the middle of the data set. Since there are 2 values on the left of 72, there must be 2 values on the right. The data set is also in order from least to greatest, so we know that the last value has to be over 72. Because it is placed to the right of 72. The only value of the options that isn't greater than 72 is 70.

Answer:
π/2 or 1.57 square units
Step-by-step explanation:
The area of a sector with central angle θ is given by the formula ...
A = (1/2)r²θ
Filling in the given value, we find the area to be ...
A = (1/2)(3²)(π/9) = π/2 . . . . square units
Using 3.14 for π, this is ...
A = 3.14/2 = 1.57 . . . . square units
