The volume of a cylinder is
(pi) (radius²) (height) .
Radius = 1/2 diameter.
Radius of this pool = (1/2) (18 ft) = 9 ft
The pool is a cylinder with height of 4.5 feet.
The water in it is also a cylinder, but only 4 ft high.
Volume of the water =
(pi) x (radius²) x (height)
= (pi) x (9 ft)² x (4 ft)
= (pi) x (81 ft²) x (4 ft)
= (pi) x (324 ft³) = 1,017.9 ft³ .
The run can be made 11 meters long
6 3/4=6*4+3/4=24+3/4=27/4
z/12=27/4
4z=27*12
4z=324
z=81
The percent decrease is 80% or 80 percent
To draw a locus point you have to draw<span> the half way line through the two </span>points. You can do this by drawing<span> the line bisector through AB points. Just open your compass to ¾ of the distance AB and then </span>draw<span> two arcs from both sides of your line. Once this is done </span>draw the line passing through the two intersection points<span>.
Hope this helps :)</span>
