**Q9: **

Chloe is interested in finding the area of circles. She has studied circumference and is happy with the formula , but she has not yet looked at area.

She starts off by drawing a circle with a square drawn on the inside and another on the outside. She uses these two squares to find an initial range that the area of the circle must lie between. What range does she get?

- ABetween 30 and 32
- BBetween 30 and 36
- CBetween 16 and 24
- DBetween 16 and 36
- EBetween 20 and 24

By combining sections to make full squares, she decides she can comfortably improve her estimated range. She counts a further 8 squares inside the circle and a further 4 outside the circle. What is her improved range for the area?

- ABetween 24 and 32
- BBetween 16 and 20
- CBetween 30 and 32
- DBetween 32 and 36
- EBetween 20 and 24

Chloe decides to take a more thorough approach to work out the area of her circle. She cuts it up into eight identical sectors and places them together to make a βparallelogram,β as seen in the given picture. She knows that the height of the parallelogram must be close to one radius, 3, and that the base of the parallelogram must be approximately half the circumference of the circle, which she knows is . To the nearest hundredth, what is the area of the circle?

Chloe wants to come up with the general formula for a circle. She realizes that if she divides her circle into more sectors and combines them, the shape gets closer to a parallelogram. If she split up her circle into infintely many sectors, the shape would tend to a perfect parallelogram. She knows the height of her parallelogram would become the radius of the circle, so she calls it . She also knows that the base is half the circumference, . Work out the area of the parallelogram to find a formula for the area of a circle.
