Rank the following circles from the largest area to the smallest area.

- circle A has a diameter of 8 cm

- circle B has a radius of 5 cm

- circle C has an area of 20pi cm2

Step-by-step explanation:

area of circle = pi * r²

so, area depends on r²

Radius of circle A = 8/2 = 4cm; r² = 16

Radius of circle B = 5 cm ; r² = 25

Radius of circle C: area = pi * r² = 20 pi

Radius of circle C, r² = 20

Hence, the order is : B> C> A

the radius is 2 times the diameter.
