Answer:
Option A , (0, 20); y equals one over eighty times x squared plus 20
Step-by-step explanation:
The equation of parabola is given by
(X-h)^2 = 4p(Y-k)^2
In this case h = 0
So we get
Y = X^2/4P +k
Focus point is (h, p+k) , p+k = 40
Hence h, k = (0,20)
P = 40-k = 20
Equation Y = X^2/80 +20
Hence, option A is correct
The formula for a cone is 1/3 πr^2 * h.
1/3 * 3.14(6)^2 * 8
1/3 * 3.14(36) * 8
1/3 * 113.04 * 8
37.68 * 8
301.44
The volume is 301.44 cubic inches.
