Find the surface area and volume of a sphere with a radius r = 0.8 ft. Round your answer to the nearest tenth. A. 7.8 ft2; 2.6 ft3 B. 8.4 ft2; 1.8 ft3 C. 8.0 ft2; 2.1 ft3 D. 8.2 ft2; 2.3 ft3

Surface area of a sphere = 4πr²

Surface area of the sphere = 4π (0.8) ² = 8.0 ft²

Volume of a sphere = 4/3 πr³

Volume of the sphere = 4/3 π (0.8) ³ = 2.1 ft³

Answer: Surface area = 8.0 ft² and volume - 2.1 ft³ (Answer C)
