Example Problem. Let’s plug the radius value 5 into the formula SA = 3πr 2. 3.) The surface area of the hemisphere is 75π. The total surface area is conceptualized as the addition of the area of its curved surface (CSA) and the area of the perfectly round base surface. For a hemisphere, if its radius 'k' is given, then its entire surface area can be given by: TSA of a hemisphere = Curved Surface Area of that hemisphere + Base Area = 2 π k2 + π k2 = 3 π k2.Formula. Volume of Hemisphere = (2/3)πr³. Curved Surface Area (CSA) of Hemisphere = 2πr². Total Surface Area (TSA) of Hemisphere = 3πr². where, r = radius, π = 3.14. A Hemisphere is a half sphere, one half of a sphere or globe that is divided by a plane passing through its center. A Hemisphere is a half of a sphere on one side of a great ... rent outdoor bean bags xa
