Since the area of a circle is π

, and our radius is 9 we know the total area to be 254.469, and the ratio of sector area to total area is 169.56/254.469 = .6663. There are 360 degrees in a circle, so:

≈ 240°
240 degrees
The correct proportion is 16/36=12/27
The answer is 13.5*3600=48600/1000cause you already have your meters per second. 13.5m/a and there are 3600 seconds in an hour then you divide that by the meters 1000 and you get **48.6**
Well to find the are of a triangle is like finding the are of a rectangle but in half so multiply 110 by 2 to get the original answer before it was divided by 2:
110×2=220
now we need to find out how many 10 are in 220:
220÷10=22
so the height of the triangle would be 22 ft
hope this helped
