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
