Answer:
Step-by-step explanation:
volume of a cylinder=πr^2*h
226.2=3.14*8*r^2
226.2=25.12*r^2
226.2/25.12=r^2
9=r^2
=r
3=r
radius =3 feet
If not the answer that I got is 26/57 = [849 x(x= 372.25)]/5
Answer:
-3.25/-1.5
Step-by-step explanation:
In order to find slope, you have to subtract y1(4) from y2(3/4) and put that over x1(2) subtracted from x2(1/2).

Answer: y = 2*cos(3pi*x) + 5</h3>
======================================
The general template for cosine is
y = A*cos(B(x-C)) + D
where,
|A| = amplitude
B = 2pi/T, with T being the period and T = 1/f, f is the frequency
C = determines horizontal phase shift
D = determines vertical shift, and is midline
---------------
In this case,
midline = 5 means D = 5
amplitude = 2 means A = 2
frequency = 3/2 means the period is T = 2/3, which is the reciprocal of the frequency, so B = 2pi/T = 2pi/(2/3) = 3pi
There is no mention of a phase shift, so C = 0.
---------------
All together we have
A = 2, B = 3pi, C = 0, D = 5
So,
y = A*cos(B(x-C)) + D
y = 2*cos(3pi(x-0)) + 5
y = 2*cos(3pi*x) + 5
