Cylinder Volume
V = hπr²
154 cm³ = 16 cm × 3.14 × r²
154 cm³ = 50.28 cm × r²
r² = 154 cm³ : 50.28 cm
r² = 3.0625 cm²
r = 1.75 cm
d = 2r
d = 2 × 1.75 cm
d = 3.5 cm
So, the diameter of the Cylinder is 3.5 cm

Answer:
<em>The actual width of the hair is 20 / 150 = 0.13 mm</em>
Step-by-step explanation:
<u>Scaling</u>
Objects can be represented in a reduced or augmented size by using scaling which is basically multiplying or dividing by a constant factor. We use scaling in several applications of real-life.
The human hair is magnified 150 times by a micro-phtograph. This is the scale factor.
The hair can be seen 2 cm wide in the photograph.
Converting to millimeters, 2 cm = 2*10 = 20 millimeters.
The actual width of the hair is 20 / 150 = 0.13 mm
.5, .76 are terminating
the square root of two, pi are terminating
Answer:
Let's find out!
Step-by-step explanation:
So we have to set up an equation
Let x= # of ribbons that can be cut
Thus:
So, we cannot have 36/7 ribbons! It's not possible!
So we just simplify!
There we go! She can cut 5 ribbons off!
I'll let you figure out the last one!
Hope this helps!
P.S. Stay Safe!
