Answer :
Answer
S = 1134.11 in²
V = 3591.36 in³
Explanation
The surface area of a sphere is given as
S = 4πr²
where
π = pi = 3.14158
r = radius of the sphere = ½ (Diameter of the sphere) = ½ (19) = 9.5 in.
S = 4πr²
S = 4 × 3.14158 × (9.5²)
S = 1134.11 in²
The volume of a sphere is given as
Volume = (4/3) × πr³
Volume = (4/3) × 3.14158 × 9.5³
Volume = 3591.36 in³
Hope this Helps!!!
