Answer:
Step-by-step explanation:
Because we are told equivalent expressions for y and z we can plug those in to 2(y+z).
Then simplify by combining like terms of the expressions. Values ending in x^2 can be combined with each other.
Now we can distribute the 2 by multiplying each value in the parentheses by 2.
1)
The formula for calculating the cone volume is:
Data:
V (volume) = ?
h (height) → h = 12 in
d (diagonal) = 9 in , if: d = 2*r , soon: 9 = 2*r → 2r = 9 → r = 9/2 → r = 4.5 in
Use:
Solving:
2)
The circle area formula is:
Data:
A (area) = ?
d (diagonal) = 19 Km , if: d = 2*r , soon: 19 = 2*r → 2r = 19 → r = 19/2 → r = 9.5 Km
Use:
Solving:
3) False, because it's the volume, the number of cubic units needed to fill a space.
