Answer:
The arc length of a circle is 3.14 m or 1π m
Step-by-step explanation:
First of all we have to calculate the circumference of the circle and then extract the portion that corresponds to 90°
To solve this exercise we need to use the circumference formula of a circle:
c = circumference
r = radius = 2m
π = 3.14
c = 2π * r
we replace the known values
c = 2 * 3.14 * 2m
c = 12.56m
As we know a circle is represented with 360 ° and they tell us that the angle is 90 °, so we have to know the relationship with respect to the total
90° / 360° = 1/4
Now we multiply this number by the circumference and we will obtain the length of the arc
12.56m * 1/4 = 3.14
The arc length of a circle is 3.14 m or 1π m
Answer:
$19.62
Step-by-step explanation:
To round 19.623 to the nearest cent consider the thousandths’ value of 19.623, which is 3 and less than 5. Therefore, the cents value of 19.623 remains 2.
$19.623 rounded to the nearest cent = $19.62
It would be 8,000 it's simple hope i could help
100+25*12=
100+300=
400
400-320=80
I=PRT
I=80
P=principal=320
T=1 year
R=?
80=320*1*?
80=320?
divide both sides by 320
0.25=?
that is 25%
answer is 25%
[20 2/3]/3 can be rewritten as an improper fraction.
20 2/3 = 62/3. Now we divide 62/3 by 3, which is the same as multiplying by 1/3.
62/9 is the number of hours each day, or 6 8/9 hours. Almost 7 hours. And this makes sense, as 20 2/3 is almost 21 hours.
