Formula to find volume in a cone is
V = pi • radius^2 h/3
So we fill in the numbers
V = pi •
the radius is half of diameter,
The diameter is 5
So it’s
V = pi • 2.5
since it’s half of 5
V = pi • 2.5^2 h/3
the height is 8 so we fill it in
V = pi • 2.5^2 8/3
When calculated, you get..
52.36
Idk if I did it right, someone correct me if I’m wrong.

Answer: 40.6Cm^3

Step-by-step explanation:

The other answer for the most part is correct, except they got the high wrong. The slant height is 8, you can figure out the actual height with the Pythagoras theorem.

a^2+b^2 = c^2

5^2 + b^2=8^2

b = square root 39

b = 6.2

The formula for a cone is: 1/3 pi*r^2*h

Now we plug in our numbers

The diameter is 5 so our radius is 2.5

Our height is 6.2

1/3 * Pi* 2.5^2 * 6.2

12.9 * 3.14

   40.6
