To find the volume of a cylinder it's
πr² x height.
So π x 10² x 10 would be the equation.
I would do it but I don't have a scientific calculator on me.
Answer:
x = 11°
4x = 44°
Step-by-step explanation:
Line BC || Line EF... (given)
BF is transversal.
is exterior angle of 
Hence, by remote interior angle theorem of triangle, we have:

Answer:
17
Step-by-step explanation:
2x - 7 = 27
2x = 34
x = 17
487 is almost 500, so we will approximate 487 as 500.
310 is just over 300, so we will approximate 310 as 300.
300+500=800 (estimation)
310+487=797 (actual)
Answer:
D
Step-by-step explanation:
Because Y=12=4×3
So if you multiply 4×3 you will get 12.
