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

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

a - base

b - exponent

so,

the base is 8the exponent is 3the exponent tells you to multiply 8 together three timesthe expanded form is 8*8*8

Ithink if ur looking for a ratio it would be 12: 3
