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
First you gotta look for the value of the 25% in the 40$ So it will be
25&=0.25
0.25x40=10
Now all you gotta do it’s
40-10=30
You subtract becaus le they ask you to find the price before it was increased so that why you gotta subrtract it
100
explanation: those two angles are supplementary which add up to be 180.

Answer:
John needs 217 tiles.
Rate of change is 1.9 tiles per square foot
Step-by-step explanation:
Hallway area=3•38=114 ft²
Rate of change=190/100=1.9 tiles/ft²
Tile total=
T=area•rate
=114•1.9
T=216.6
(Round up because tiles are sold as whole units)
Total tiles=217
