You run one lap around a mile track every 8 minutes. your friend runs around the same track every 10 minutes. you both start at the starting line at the same time

slope is 35 and 20 miles is the y-intercept.

step-by-step explanation:

34.5 cm

step-by-step explanation:

generally for a circular segment of angle, θ° and radius r

arc length

= (θ/360) x circumference

= (θ/360) x 2πr

in our case, θ = 60°, π=3.142 and r = 33 cm

substitute into above formula

arc length

= (60/360) x 2(3.142)( 33) = 34.5 cm
