Question

Which of the following formulas could be used to determine the surface area of a cylinder sandwiched between one cone and half of a sphere?

a. SA = 4πr²
b. SA = 2l l + i²
c. SA = 2π rh + 2π r²
d. SA = π r l + π r²
e. SA = 2lw + 2lh + 2wh
f. SA = 2B + Ph

Answer 1

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).
