Question: how do you calculate the volume of a hemisphere?
Answer: Diameter of a hemisphere: d = 2 * r , Volume of a hemisphere: V = 2/3 * π * r³ , Base surface area of a hemisphere: Ab = π * r² , Cap surface area of a hemisphere: Ac = 2 * π * r² , Total surface area of a hemisphere: A = 3 * π * r² ,
