Depth of pool + 1.8 = 6.1
D = 6.1 - 1.8 = 4.3 feet
The area of a whole circle is (pi) (radius²) .
So the area of half of it would be <em>(1/2) (pi) (radius²) .</em>
If you don't know the radius, then you can use the formula
Area = (1/8) (pi) (diameter²) .
r and 5 both make 197
r would be a use of a number that isn't known unless you rearrange the equation
The equation would be 5r = 197 or 5 x r = 197
So you could make r the subject,
And to find it, you could divide 197 by 5
197 / 5 = r
Which then would make r = 39.4
