Question

What's the area of an ellipse with the major axis 20 m and the minor axis 10 m? Round your answer to the nearest whole number. A. 200 m2 B. 628 m2 C. 50 m2 D. 314 m2

Answer 1

Answer

Find out the area of an ellipse .

To proof

Formula

$Area\ of\ an\ ellipse = \pi a b$

where a and b are major and minor axis of the ellipse

As given

In an ellipse

the major axis 20 m and the minor axis 10 m

$\pi = 3.14$

put all the value in the formula

we get

Area of an ellipse = 3.14× 10× 20

                             = 628 m²

option (B) is correct

Hence proved
