Area of a circle = pi*radius2
A = 5.093 cm2
the answer is 20.54
Using 3.14 as Pi the area of circle is: 200.96
It depends on the ratio of what of the circle? Its circumference, diameter, area?
Multiply the diameter by the value of Pi - and you'll have your answer !
That would depend on its radius which has not been given but the area of a circle is pi times radius squared
Circumference of a circle = 3.14 x d 3.14 x 8 = 25.12 Therefore the circumference of a circle with the diameter of 8cm is 25.12cm.
A square of perimeter 32cm has 4 sides of length 8cm. Area = Side1*Side2 Area = 8cm*8cm Area=64cm2
A rectangle that is 2cm by 4cm has an area of 8cm. It also has a perimeter of 12cm.
The diameter of a circle may found by dividing the circumference by pi. 8cm/3.1416=2.546cm
