Raina spent $72 on fruit at the grocery store. She spent a total of $80 at the store. What percentage of the total did she spend on fruit?

answer: 88

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

m∠a is 90°

m∠b is 40°
