Factorise please solve this question (a+b)^3 +8c^3

(a+b)^3 + (2c)^3

(a+b+c) [(a+b)^2 - 2c(a+b) +(2c)^2]

(a+b+c) (a^2+2ab+b^2-2ac-2ab+4c^2)

(a+b+c) (a^2+b^2-2ac+4c^2)

the figures below are made out of circles, semicircles, quarter … find the area and the perimeter of each figure and give your answers as a completely simplified exact value in terms of π (no approximations). remember that we'll also have to cut whatever areas we get in half, since we're only dealing
