Answer: Circumference ≈ 70.45 cm
Step-by-step explanation:
To find the circumference of a circle with a radius of 11.2 cm, we can use the formula:
Circumference = 2 * π * radius
Given that π is approximately 3.142 and the radius is 11.2 cm, we can substitute these values into the formula:
Circumference = 2 * 3.142 * 11.2
Calculating this gives us:
Circumference = 70.4512 cm
To round the answer to two decimal places, we look at the third decimal place. Since it is less than 5, we keep the 4 in the second decimal place and drop the remaining decimal places. Thus, the final answer, rounded to two decimal places, is:
Circumference ≈ 70.45 cm
