WebDetermine the surface area of a sphere having a radius of 7 cm. Solution: Given radius = 7 cm The Surface Area of a Sphere (SA) = 4πr2 Square units SA = 4× (22/7)× 7 2 SA = 4 × 22 × 7 SA = 616 cm 2 Therefore, the surface area of a sphere = 616 square units. Example 3: Find the volume of a sphere in terms of π, if the radius is 9 cm? Solution: WebThe correct answer is 6.12 ft. Plug the value of into the equation so that Multiply both sides by 3 to get Then divide both sides by to get Then take the 3rdroot of both sides to get 3.06 ft for the radius. Finally, you have to multiply by 2 on …
