Answer:
42.2 cubic inch
Step-by-step explanation:
Applying,
V = πr²h/3.................... Equation 1
Where, r = radius of the circular base, h = height of the cone, π = pie.
But,
r = P/2π..................... Equation 2
Where P = circumference of the circular base.
Substitute equation 2 into equation 1
V = π(P/2π)²(h)/3
V = P²h/12π.................. Equation 3
From the question,
Given: h = 18.4 in, P = 9.3 in
Constant: π = 3.14
Substitute these values into equation 3
V = (9.3²)(18.4)/(12×3.14)
V = 42.2 cubic inch
Do you have any idea on how this is solved? When (h, k) both equal 0; you get a special formula. x^2 + y^2 = r^2 --- x^2 + y^2 = 25
And you can kinda look at the graph and guess which one it'll be.

Step-by-step explanation:
Thank you for posting your question here at brainly. The quadratic function that models the data as a function of x, the number of weeks is the second one which is "P(x) = 13x2 – 10x + 350; 1,102 fish". I hope the answer will help you.
We have been given that function that models the population to be:
p(t)=7te^(-t/12)
we are required to compute for the time taken for the percentage of infected people to be maximum.
from the interval given, the maximum number will be at the point p'(t)
from the function;
p'(t)=-7/12e^(-t/12)(t-12)
equating this to zero and solving for t we get:
-7/12e^(-t/12)(t-12)=0
t=12
hence it will take a maximum of 12 days for infection to reach it's maximum percentage.
