Find the circumference and area of a circle with a radius of 4.5cm (use 3.14 for pi and round to tenth place and include proper units)
Circumference
C = 2 * π * r
C = 2 * 3.14 * 4.5
C = 28.26 cm
Area
A = π * r^2
A = 3.14 * (4.5)^2
A = 63.59 cm^2
Therefore, the circumference of the circle is 28.3 cm and the area of the circle is 63.6 cm^2.
