WebMar 12, 2024 · The formula for the surface area of a sphere is 4 π r 2, where ‘r’ is the radius of the circle. Thus, to calculate its value we first need to know the radius of a sphere. Let the radius of the sphere be ‘r’ and surface area of the sphere be ‘S’, then, the formula can be expressed as: Surface area of sphere (S) = 4 π r 2 WebCSA of hemisphere = (1/2)surface area of the sphere CSA = (1/2)4πr 2 CSA = 2πr 2 The curved surface area of a hemisphere = 2πr2 square units. The total surface area of the sphere = Curved surface area of sphere + base area We know that the base of the hemisphere is circular in shape, use the area of the circle. TSA = 2πr 2 + πr 2 = 3πr 2 …
WebOct 27, 2024 · In the formula for the surface area of a sphere, \ (4\) and \ (\pi \) are constants. The surface area of a sphere directly depends on the radius of the sphere. \ (A \propto {r^2}\) If we compare two spheres of different sizes, the sphere with a greater radius will have a larger surface area. 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.
