4. Find circumference and area of circle with a radius of 4.5cm. (use 3.14 for pi and round to tenth place and include proper units)
Circumference = 2 * π * radius
Circumference = 2 * 3.14 * 4.5cm
Circumference = 28.3 cm (rounded to the nearest tenth)
Area = π * radius^2
Area = 3.14 * (4.5cm)^2
Area = 3.14 * 20.25cm
Area = 63.6 cm^2 (rounded to the nearest tenth)
