What is the scale factor? A (3, 6) B ( 12, 9)> A’(1, 2) B’ (4, 3)

3:1

Step-by-step explanation:

If you divide all the coordinates in the first set by 3, you will get the second set's coordinates. Therefore, the ration to "the first set" to "the second set" is 3:1

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
