Answer:
3 cubic inches
Step-by-step explanation:
Volume of cone shown= 6 cubic inches
Let the base diameter be 2x.
Therefore, radius= x
Since the base diameter is the same, the base area is the same.
Using the formula, volume of cone
Subst. the known value of into the equation.
Thus, volume of cone= 1(3)= 3 cubic inches
Answer:
Step-by-step explanation:
Let the fraction be .
That would mean:
(1) x+y = 19
&
(2) y+8 = 2x or 2x = y+8
In order to use substitution, we multiply equation by 2:
(3) 2x+2y = 38
Then we substitute equation (2) into (3):
y+8 + 2y = 38
3y + 8 = 38
3y = 30
y = 10
Substitute this into equation (1)
x + 10 = 19
x = 9
Therefore the fraction would be:
