(D) The total surface area of a cone is given by the formula: $TSA = \pi r(r + l)$,where $r$ is the radius and $l$ is the slant height.Given: $r = 5 \, cm$ and $l = 9 \, cm$.Substituting the values into the formula:$TSA = \pi 	imes 5 	imes (5 + 9)$$TSA = \pi 	imes 5 	imes 14$$TSA = 70 \pi \, cm^2$.Using $\pi \approx \frac{22}{7}$:$TSA = 70 	imes \frac{22}{7} = 10 	imes 22 = 220 \, cm^2$.Therefore,the total surface area is $220 \, cm^2$.

The radius of a cone is $5 \, cm$ and slant height is $9 \, cm$. The total surface area of the cone is $\ldots \ldots \ldots \, cm^2$.
