Answer:

Step-by-step explanation:
step 1
Find the volume of the cylinder
The volume of the cylinder is equal to

we have
---> the radius is half the diameter

substitute

step 2
Find the volume of the cone
The volume of the cone is equal to

we have
we have
---> the radius is the same that the radius of the cylinder

substitute

step 3
Find the volume of the plastic object
we know that
The volume of the plastic object is equal to the volume of the cylinder minus the volume of the cone
so

assume


Answer:
(-1, -2.5)
Step-by-step explanation:
(3, 0) is the midpoint between (2, 2) and (4, -2)

Answer: -42v + 70
Step-by-step explanation: You’d multiply -7 with the figures in the brackets, then you’d group like terms then subtract -7v from -35v.
1. -35v + 70 - 7v
Negative multiplied by negative is a positive
2. -35v - 7v + 70
Group like terms
3. -42v +70
Subtract
