Answer:

Step-by-step explanation:
Given



Required
The volume of the remaining cylinder
Before the cut-out, the cylinder has a volume (V) of:

After the cut-out, the cylinder has a volume of:
![V = \pi [R^2 -r^2]h](https://tex.z-dn.net/?f=V%20%3D%20%5Cpi%20%5BR%5E2%20-r%5E2%5Dh)
So, we have:
![V = 3.14* [6^2 -5^2]*15](https://tex.z-dn.net/?f=V%20%3D%203.14%2A%20%5B6%5E2%20-5%5E2%5D%2A15)
![V = 3.14* [36 -25]*15](https://tex.z-dn.net/?f=V%20%3D%203.14%2A%20%5B36%20-25%5D%2A15)


Answer:
C is the correct answer
Step-by-step explanation:
A) 25-18 which equals 7
7 is NOT bigger than 8
B) 0.5x18= 9
7 is NOT bigger than 9
C) 18÷6=3
3 IS bigger than 2 so is correct
D) 18÷4= 4.5
4.5 is NOT bigger than 3
hope this helps!
Area of a triangle= 1/2bh
14x5.5=77
77/2=38.5cm^2
