Find the surface area of the composite 3D figure below. leave in terms of pi, numerical value only

Given:

The diameter of the cylinder = 34 m

So, the radius (r) = 17 m

The height (h) of the cylinder = 12 m

The slant height (l) of the cone = 20 m

To find the surface area of the given figure.

Surface area of the given fig = surface area of cylinder + surface area of the cone

Formula:

The surface area of the cylinder is

The surface area of the cone is

Now,

The surface area of the cylinder is given by

The surface area of the cylinder is 986π m²

The surface area of the cone is given by

Thus, the surface area of the cone is 340π m²

The surface area of the composite figure is given by

Surface area = Surface area of cylinder + Surface area of cone

Substituting the values, we get;

Thus, the surface area of the composite figure is 1326π m²

1; 35 is the ratio
