AfilCa [17]

Answer:

1)

Area

2)

1/2

3)

Radius

Step-by-step explanation:

Area of circle=πr².

and circumference of circle = 2πr.

Hence, to describe  the relationship between the area of a circle and its circumference.

The Area of circle is 1/2 times the radius times the circumference.

( Since,

Area=1/2 × r× 2πr

Area=πr² )
