Answer:
~8.7
Step-by-step explanation:
So we know that the formula for volume is 3.14 * r^2 * h.
So first we do 1738/23 to get an ugly ~ 75.6 Now he have to square root that to get r.
The square root of 75.6 is ~ 8.7
To find h(6), we must plug in 6 into the function.
h(x) = x^2 - 2x - 5
h(6) = 6^2 - 2(6) - 5
= 36 - 12 - 5
= 36 - 17 = 19
