Question

Find the area of the following ellipse Use = 3.14 and round to nearest tenth. a = 7 in.; b = 9 in. area = sq. in.

Answer 1

Area= 197.82 sq. in.

Explanation:

We know that Area of ellipse=a×b×π

where a is the length of semi major axis

and b is the length of semi minor axis

Here, a=7 in.

and b=9 in.

so, area of ellipse=3.14×7×9

= 197.82 sq. in.

Hence, Area=197.82 sq. in.

Answer 2

area = PI x a x b

area = 3.14 x 7 x 9

area = 197.8 sq. in.
