To find the circumference, we can use the formula C = 2πr, where r is the radius of the circle.
To find the area, we can use the formula A = πr^2.
Let's say the radius of the circle is r units.
Circumference: C = 2πr
Area: A = πr^2
Rounding to the nearest tenth:
C = 2πr ≈ 2 * 3.14 * r ≈ 6.28r
A = πr^2 ≈ 3.14 * r^2
Note: Since no specific value for r is given, we cannot determine the exact circumference and area.
