Answer 1

90/360 x 3.14 x
`2^(2)`. (put into calculator)

Explanation:

This is a sector of a circle we can see that there is a right angle (90 degrees) so we can say there is 90/360 of a circle.

The formula for the area of a circle is pi times radius squared.

We can use this but also need to use 90/360.

We can say the area of the shape is 90/360 x 3.14 x
`2^(2)`.
