The radius of a circle is 6 miles. what is the length of a 135° arc? 135° r=6 mi
PSYCHO15rus [73]
This is the formula to determine the length of arc
length of arc = angle/360° × circumference

First we should find the circle circumference
c = 2 × π × r
c = 2 × 3.14 × 6
c = 37.68 miles

Second find the length of arc
length of arc = angle/360 × circumference
length of arc = 135/360 × 37.68
length of arc = 3/8 × 37.68
length of arc = (3 × 37.68)/8
length of arc = 113.04/8
length of arc = 14.13

The length of arc is 14.13 miles

Ok so they loose $200 per month.

10 students go for 1 hour per week and pay $15

10x15=150

$150 per week

4 weeks in the month

$150 x 4 = $600
