Answer:

Area of the flying saucer = $907.46 ft^2$

The Flying saucer is in the shape of a circle.

Area of the circular flying saucer= $\pi *r*r$

: $\pi =\frac{22}{7} =3.14$

Area= $3.14*17*17$

Area of the flying saucer $=3.14*289\\\\ =907.46 ft^2$

So, the area of the flying saucer is $907.46 ft^2$
