first of all, you need to assume that this shape is like a cone. So cone has a height and you can find it by using Thales's theorem. so it would be
[tex] \frac{x}{x + 6} = \frac{4}{8} [/tex]
x is 6. So the total height of the cone has founded.
To find the volume of this frustum we have to subtract the volume of the small cone(at the top of the frustum) which has 6 cm in height from the big cone with 12 cm in height.
big cone Volume: ⅓(8²π×12)
-
small cone Volume: ⅓(4²π × 6)
=
frustum volume : 224π

The formula for the nth square number is S, -n². Use the formula to find the 19th square number.
The 19th square number is (Simplify your answer.)
The nth square number of the value given is the squared value of 19, which is 361
The nth square number , S is related by the formula :
S = -n²n = nth termGiven that , n = 19
The nth square number , where n = 19 can be calculated thus:
S = -19² = 361
S = (-19) * (-19)
S = 361
Therefore, the 19th square number is 361
