20 - 4 - 2 = 14. A negative number is just like subtracting it.

These two cylinders are congruent. cylinder a has a radius of 4 centimeters. cylinder b has a volume of 176π cubic centimeters.

Dafna11 [192]

The height of cylinder b is 11 cm.

<h3>How to measure the volume of a cylinder?</h3>

The volume of the cylinder is related to the capacity of this geometric figure. Remember that the cylinder or circular cylinder is an elongated and rounded geometric solid.

The formula for the volume of a cylinder is given by:

$V = \pi.r^2.h$

Where:

V: volume
π (Pi): 3
r: radius
h: height

In this case, as the cylinders are congruent, both will have the same radius, thus:

$V = \pi.r^2.h\\176\pi=\pi(4)^2(h)\\h=11$

Find an equation of the line parallel to −5x+7y=3 that passes through the point (9,−4). If possible, write the equation in slope

saul85 [17]

From the original equation we have:

$-5x+7y=3$ $7y=5x+3$ $y=\frac{5}{7}x+\frac{3}{7}$

The slope of this line is 5/7 and for the new equation to be parallel to the original must have the same slope, and using the point-slope formula we have:
