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) show your work
First, we will calculate the circumference of the circle:
Circumference = 2 * π * radius
Circumference = 2 * 3.14 * 4.5
Circumference ≈ 28.3 cm
Next, we will calculate the area of the circle:
Area = π * radius^2
Area = 3.14 * (4.5)^2
Area ≈ 63.6 cm²
Therefore, the circumference of the circle with a radius of 4.5 cm is approximately 28.3 cm and the area is approximately 63.6 cm².
