Csa of half sphere
WebA 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 circle. I geometry, hemisphere is defined as an exact half of a sphere. ... (CSA) = 2πr² = 2 * 3.14 * 2² = 6.28 * 4= 25.12 Step 3: Find the total surface area (CSA). WebStep 1: Note the radius of the sphere. Here, the radius of the ball is 9 inches. Step 2: As we know, the surface area of sphere = 4πr 2, so after substituting the value of r = 9, we get, surface area of sphere = 4πr 2 = 4 × 3.14 × 9 2 = 4 × 3.14 × 81 = 1017.36. Step 3: Therefore, the surface area of the sphere is 1017.36 in 2.
