1) S= 9pi +24 units² 2) V=18pi u³
Since the figure is made of a rectangle, and a quarter of a circle,
then Let's calculate it by parts.
1) The surface of the rectangular part

2) Given the fact the we need 1/4 of the area of a circle. So:

Finally, The surface area of the solid is about 9pi +24
The Volume:
Considering that the rectangle, rotating produces a solid called cylinder
and that a quarter of a circle rotated around the x produces a hemisphere
Let's calculate it
Volume of the cylinder

And the Volume of the hemisphere (half of the volume of a sphere)

And the Volume of the solid is about 90 pi
