You can use the formula a=h/h to find the batting average a of a batter who has h hits of .290 and has been at bat 300 times, how many hits does the batter have?

(a) the volume of the cone is 20/3 in3

hence, option a is correct.

let's first notice, the center of the hyperbola is at the origin, since the focus points are equidistantly 3 units away from the origin, that also means that the distance "c" from the center to either focus is 3.

it should also be notable that, the traverse axis for this hyperbola is vertical, or namely over the y-axis and therefore, the positive fraction will be the one with y-variable.

the traverse "a" component or distance from the center to either vertex is not 2, is more than 2, so we can safely put it at √5 ≈ 2.24.
