C is the answer
they have equivalent sides and equivalent measurements
20 - k/15 = 17
20 - 17 = k/15
3 = k/15
k = 45
Answer:
B =
*r^2
(Base of the cone)
Step-by-step explanation:
The volume of the cone is always 1/3 of the volume of a cylinder with the same radius and height.
Volume of the cylinder
V_cylin = (
*r^2 )* h
Where
r is the radius
h is the height
This means the volume of the cone is equal to
V_cone = (1/3)* (
*r^2 )* h
By looking to the equation of the problem
V=(1/3)Bh
We can easily deduce that
B =
*r^2
(Base of the cone)
Answer:
−7
Step-by-step explanation:
Answer:
y = -
x
Step-by-step explanation:
Given that y varies directly with x then the equation relating them is
y = kx ← k is the constant of variation
To find k use the condition x = 24, y = - 6
- 6 = 24k ( divide both sides by 24 )
= k , that is
k = - 
y = -
x ← equation of variation
