please put step by step solutions

Example: Determine the surface area of a hemisphere. A sphere has radius \( 8.0 \mathrm{~cm} \). What is the surface area of the hemisphere to the nearest tenth of a square centimetre? Example: The surface area of a tennis ball is approximately \( 127 \mathrm{~cm}^{2} \). What is the radius of the tennis ball to the nearest tenth of a centimetre? Example: The circumference of a sphere is \( 25 \mathrm{~cm} \). What is the surface area of the sphere?
