Question

If the curved surface area of a sphere is $68m^2$, then which of the following option is correct about the total surface area of the sphere.

• A. Total surface area $>68m^2$
• B. Total surface area $=68m^2$
• C. Total surface area $<68m^2$
• D. None of the above

Answer 1

The correct option is B Total surface area $=68m^2$


For a sphere the total surface area is equal to the curved surface area.
Hence,
Curved surface area = Total surface area $=68m^2$
