Sphere, cylinder, and/or cone. which shape possesses a set of parallel cross sections that are congruent circles

Cross section is generally a two-dimensional plane figure. If the cone is cut parallel to the base, along LM, the result would be the base of the cone, which in cross section, is just a circle.

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

just get this app called photo math it should be able to do those
