Answer:
139
Step-by-step explanation:
First we need to find diameter 132/3.14=42 rounded
Then we halve it to find radius 42/2=21
Formula for area is radius x radius x 3.14
21 x 21 = 441 x 3.14 = 138.74 round up is 139
Answer:

Step-by-step explanation:
Equation of a line:
The equation of a line that passes through point
, in point-slope form is given by:

In which m is the slope.
Finding the slope:
To find the slope of a line, we need a pair of points. The slope is given by the change in y of these points divided by the change in x.
In this question:
Points (2,2) and (4,6).
Change in y: 6 - 2 = 4
Change in x: 4 - 2 = 2
Slope: 
So

I can consider any of these two points
, i will use (2,2). So

Answer:
9n + 15
Step-by-step explanation:5XN + 5X3 + 4N = 5n + 15 + 4n = 9n + 15
