Final answer:
The correct formula to determine the surface area of a cylinder sandwiched between one cone and half of a sphere is option c. SA = 2π rh + 2π r².
Step-by-step explanation:
The correct formula to determine the surface area of a cylinder sandwiched between one cone and half of a sphere is option c. SA = 2π rh + 2π r².
This formula accounts for the curved surface of the cylinder (2π rh) and the surface area of the bases, which are circles (2π r²).
