A central angle of 62 intercepts an arc length of 90 units what is the radius or the circle? Help ASAP

l = 90, x = 62, r = ?

arc length is:

l = x · 2πr / 360

90 = 62 · 2πr / 360

360 · 90 = 360(62 · 2πr) / 360

32400 = 389.36r

32400 / 389.36 = 389.36r / 389.36

r = 83.2

Step-by-step explanation:

1. label the values and write down the arc length formula

2. replace the l and x by their values

3. multiply both sides by 360 to get rid of the 360 at the denominator

4. since 360 cancel out 360, you're left with 62 · 2πr. multiply them to be able to solve for r. (you can use 3.14 for pi)

5. divide both sides to get r by itself

14.3

step-by-step explanation:

add all the numbers together.

9 + 12 + 15 + 16 + 17 + 17 = 86

now, divide 86 by how many numbers we have: 6.

86 / 6 = 14.3
