vekshin1

Answer:

251.65 Millimeters rounded to the hundredths place.

Step-by-step explanation:

The formula for the area of a circle is A=π×r^2.

Step 1: Find r, or the radius, which is half the diameter. In this case, it is 8.95.

Step 2: Square the radius that you get. In this case, the answer is 80.1025.

Step 3: Multiply the past number by π on your calculator. Some teachers allow 3.14 but be certain that your teacher allows it. In this case, π×80.1025=251.649425534

Step 4: You've got your answer! Hope this helps!
