Answer:
The height is 15 feet
Step-by-step explanation:
If you use the formula for cone height and substitute in your values:
h=3 x (V/πr^2)
h=3 x (81430.1/72^2π)
h=15
The radius will be 7.25cm
The circumference will be about 45.55
The area will be about 165.13
5:00 AM Australia is 15 hours ahead!
-x^2 - 2x + 15 in vertex form is -(x^2 + 2x - 15) = -(x^2 + 2x + 1 - 16) = -(x + 1)^2 + 16
Therefore, domain is all real numbers and range is {y|y ≤ 16}.
