using a tape measure, Susan found that the circumference of the great redwood was 1200 cm. She estimated that its diameter was 400 cm. Was her estimate a little too large or a little to small. Why?

y=mx+

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

i think the answer is b
