A. Explain why a³- b³ is equal to the sum of the volumes of the sides I, II, and III. B. Write an algebraic expression for the volume of each of the three solids. Leave your expressions in factored form.

C. Use the result from part(a) and part (b) to derive the factoring pattern a³- b³

the answer is b. 60. each interior angle in 120, so the exterior angle must be 60 in order to add up to 180

step-by-step explanation:

so then what are you asking?

step-by-step explanation:

you can't solve x because it is 2 linear equation and you only have one equation

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
