The main formula is A= 2pi r (H + r)
H= 9, and r= 11
so A= 2 *3.14*11* (9 + 11) = 1381.6 cm²
so the answer is <span>1380 cm2</span>
Formula (n-2)x180

Answer:
Cam is at 6m below the surface of the water.
Step-by-step explanation:
Ignore all info except:
Ben is 8 meters below the surface of the water.
Cam is 2 meters above Ben
So now answer this;
What is Cam's position relative to the surface of the water?
This is too simple. Cam is 2 m above Ben which means two meter closer to the surface as Ben.
Ben was 8 m below the surface. By this Cam is 2 m closer to the surface, which is 8 - 2 = 6 m.
Cam is at 6m below the surface of the water.

Step-by-step explanation:
To get the slope you have to find the difference in Y and put it over the difference in X. (x2-x1)/(y2-y1). You plug in the points and you get -1/2
