Respuesta :

Answer without rounding: 59.62075 cm2



Explanation: The general formula for the surface area of a right circular cone is A= πrl+πr2.


Using the pictures information, we have A=(3.14*1.75*9.1)+(3.14*1.75^2).

Also, we divided the diameter 3.5 cm in half to find the radius of 1.75 cm.

The final answer without rounding of course is 59.62075 cm2.
