Which of the following formulas would find the lateral area of a right cone where r is the radius and s is slant height?
2 answers:
For a right circular cone, the lateral surface area is given by,
The value of square root of h²+r² is equal to slant height s.
So replacing the value of square root of (h²+r²) by s in the formula for lateral surface area , we have
L.S.A. = pi * r * s
where s is slant height of the given right cone.
Answer: The lateral surface area of a right cone is pi*r*s.

Step-by-step explanation:
is basically the horizontal axis.
First, find the integral of x^2-25.
Remember that
integral of a constant is that constant times x.
Also that
to take the integral of a power function, add 1 to the degree and divide by that same degree.
We then get
Evaluate at -3
Then we evaluate at 0
Next, we subtract the the answer then we get
