victus00 [196]

Answer:

v = 1

u = 2

Step-by-step explanation:

Given is a special right triangle with angle measures as follows:

90-60-30

The side lengths would be :

2x- x\sqrt{3}-x

in the image it shows that the second side length (the one that sees angle measure 60) is \sqrt{3} from this we can conclude x = 1 so:

v = 1 and

u = 2

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
