Write and equation to represent the complementary angle relationship between

the arc length is found by finding the circumference of the full circle (2xpixradius) and then dividing by 4 to find just one quarter of the circle (90 degrees).

step-by-step explanation:

a fish tank full of water and then fish, regardless of the shape of it, has a certain volume.   volume is how much of something fills up the inside of a shape.   if the shape of the tank is a sphere, thr volume formula for a sphere is

we are given that the diameter of the sphere is 14, so that means that the radius is half of that at 7.   filling in to find the volume of the sphere:

do the math on that and you find that the volume of the tank is 1436.755

if there is to be 1 fish for every 693 cubic inches, we must divide the total volume of the tank by 693 to get the number of fish that will fit comfortably.

1436.755/693 = 2.07

since you can't have .07 of a fish, we round down to the nearest whole number to get that 2 fish will be able to swim comfortably in the tank.

definition: a circle is the set of all points in a plane that are equidistant from a given point called the center of the circle. we use the symbol ⊙ to represent a circle. the a line segment from the center of the circle to any point on the circle is a radius of the circle.
