A set production designer creates a right circular cylindrical PILLAR. The designer knows the amount of material used for the surface of the pillar and needs to find the height for a 2 reinforcement rod. Use A = Trh + ar² , where rrepresents the radius, h represents the height of the pillar, and A represents the surface area of the pillar. What is a formula for h in terms of the other variables that can be used to find the height? A – Tr² A h = 2rr A+ ar? B) h = 2rr A h = A D) h = 2nr 1
