Calculate the volume of the cylinder, where a = 18 and b = 11. Use 3.14 for pi and round your answer to the nearest tenth.
cupoosta [38]

Answer:

Volume of cylinder =2797.7

Step-by-step explanation:

Let a be diameter and b the height of the cylinder

Then\ radius(r)=\frac{diamater\ (a)}{2}\\\\r=\frac{18}{2}\\\\r=9

Volume of cylinder =\pi\times(radius)^2\times(height)

=\pi\times(9)^2\times11\ \ \ \ \ \ (\pi=3.14)\\\\=3.14\times9\times9\times11\\\\=2797.74\\\\\approx2797.7

write the slope intercept form of an equation of the line that passes through (4,3) that is perpendicular to the line Y=-3x-15
cricket20 [7]
If two lines are perpendicular, then their slopes have a product of -1 or you could say they are opposite signed reciprocals of each other.
The given equation has a slope of -3.  We know this because it is in slope-intercept form y = mx + b ...y = (slope)x + (y-intercept).

so taking the slope -3...the opposite signed reciprocal would be +\frac{1}{3}

Now we have a slope and a point... we can use them to find the b (y-intercept)
x = 4, y = 3, and m = \frac{1}{3}
3= \frac{1}{3} (4)+b
3= \frac{4}{3} +b
Using the common denominator fraction for 3, we subtract 4/3 from both sides
3= \frac{9}{3}
\frac{5}{3} =b
plug the values for m and b into the slope intercept form
y= \frac{1}{3} x+ \frac{5}{3}
