Petra walked 9 miles the first week of this month, twice that far the second week, and 6 miles the third week. how many miles has she walked all together

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

the answer is 13

step-by-step explanation:

5*5=25

12*12=144

25+144=169

169^2=13
