Yes he is correct because u do have to multiple it
Direct variation is of the form y = kx where k is a constant
So its A
Answer:
87
Step-by-step explanation:
common difference = d = 2
an = a1 + (n-1)*d
a43 = 3 + 42*2 = 87
To find the volume of the cylinder
V = pi* r^2* h
Plug in what you are given
V = pi* (6)^2* (20)
V = pi * 36 * 20
V = 720 pi
Hope this helps :)
