a. To find the surface area of a golf ball, we use the formula for the surface area of a sphere, which is 4πr². The radius (r) of the golf ball is half of the diameter, so r = 4.3 cm / 2 = 2.15 cm.

Substituting the values into the formula, we get:

Surface Area = 4 * 3.14 * (2.15 cm)² = 4 * 3.14 * 4.6225 cm² = 58.0 cm² (to the nearest tenth)

b. To find the volume of the golf ball, we use the formula for the volume of a sphere, which is 4/3πr³.

Substituting the values into the formula, we get:

Volume = 4/3 * 3.14 * (2.15 cm)³ = 4/3 * 3.14 * 9.920875 cm³ = 41.6 cm³ (to the nearest tenth)
