Ratio = \frac{\text{Students preferred hockey}}{\text{Students preferred basketball}}

         = \frac{1}{5}

         = 1 : 5

Option W is the answer.

8). Ratio of the students whose favorite sport is either baseball or soccer to the total students,

Ratio = \frac{\text{Students preferred baseball or soccer}}{\text{Total students}}

         = \frac{(3+8)}{19}

         = \frac{11}{19}

         = 11 : 19

Option O is the answer.

9). Ratio of the students who prefer soccer, basketball, baseball or hockey to those who preferred another sport,

Students who prefer soccer, basketball, baseball or hockey = 8 + 5 + 3 + 1 = 17

Students who prefer another sport = 2

Ratio = 17 : 2

What is the arc length of a circle (in meters) with a radius of 2 meters that has an arc angle of 90°?
DIA [1.3K]

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
