Answer:
I think A and C if i'm correct
Step-by-step explanation:
Answer:
in terms or pi
simplified
Step-by-step explanation:
To solve this, we are using the Cylinder's volume formula:
where
is the volume of the cylinder
is the radius of the cylinder
Remember that radius is half the diameter, so we can divide the diameter of our cylinder by 2 to find its radius: . Now, 9 1/2 inches is 9 and a half inches, so .
Replacing values:
We can conclude that the volume of our cylinder is in terms of pi, or simplified.
Answer:
57
Step-by-step explanation:
5x6=30
30+27=57
Formula for compound interest is
Interest = Amount - Principal
Interest = - P
Where r = rate in percent
t = time in years
For Jaina,
P = $300
r= 7%
t = 3 yrs
So, Interest = - 300
For Tomas
P = $400
r= 4%
t = 3 yrs
So, Interest = - 400
So pair of equations for Jaina and Tomas are
Interest = - 300
Interest = - 400
