Answer:
The area of a circle is [tex]\pi r^{2}[/tex] which is given in the question. (r is radius)
The radius is the length from the centre of the circle to the border of the circle (8cm in this case)
Area of circle:
[tex]\pi r^{2} =\pi *8^{2} =64\pi =201.06cm^2[/tex] (2 decimal places)
Circumference of circle:
[tex]\pi d[/tex] (d is diameter)
The diameter is twice the radius and it is the length of a point on the circle to the opposite point of it.
[tex]\pi d=\pi *2*8=16\pi =50.27cm[/tex] (2 decimal places)
