Answer:
Part 1) The exact value of the arc length is \frac{25}{6}\pi \ in
Part 2) The approximate value of the arc length is 13.1\ in
Step-by-step explanation:
ind the circumference of the circle
The circumference of a circle is equal to
C=2\pi r
we have
r=5\ in
substitute
C=2\pi (5)
C=10\pi\ in
step 2
Find the exact value of the arc length by a central angle of 150 degrees
Remember that the circumference of a circle subtends a central angle of 360 degrees
by proportion
\frac{10\pi}{360} =\frac{x}{150}\\ \\x=10\pi *150/360\\ \\x=\frac{25}{6}\pi \ in
Find the approximate value of the arc length
To find the approximate value, assume
\pi =3.14
substitute
\frac{25}{6}(3.14)=13.1\ in
Answer:
A. y = 1/2 x
Step-by-step explanation:
A proportional relationship between two quantities is a collection of equivalent ratios, related to each other by a constant of proportionality. In other words, if each point on the line can be put as a fraction and reduced to the same fraction, the relationship is proportional.
Step-by-step explanation:
who reported you (for no reason)?
11.05 inches.
EXPLANATION:
Firstly, lets see the unit rate for how many inches per minute.
5.2 divided by 8 is 0.65 inches every minute.
Now since there is 17 mins, simply do 0.65 inches per min x 17 mins.
11.05 inches.
Hope this helps!
