Answer:
V - 1099.55742876
SA - 769.690200129
Step-by-step explanation:
The volume of a cone is denoted by the formula:
V = 1/3 * h * pi * r^2
We can substitute in the values we are given:
V = 1/3 * 10.5 * pi * 10^2
V = 3.5 * 100 * pi
V = 350pi
This is about: 1099.55742876
The formula for the surface area of a cone is:
SA = pi * r^2 + pi * r * s
We can substitute what we have:
SA = pi * 10^2 + pi * 10 * 14.5
SA = 100 pi + 145 pi
SA = 245 pi
This is about: 769.690200129
