First, you divide the circumference (8.9) by 3.14, or π.
Cirucmference(8.9) divided by π(3.14) = the diameter (2.83439490446)
Diameter (2.83439490446) divided by 2 = radius (1.41719745223)
Now, you have to round to the nearest hundredth.
1.41719745223 rounded to the nearest hundredth is 1.42 because the second number after the decimal is your hundredths place. If the number after the decimal is 4 or less, just remove all of the digits to the right. If it's five or more, like this case where it is 7, you add 1 to the hundredths place, then you remove all of the digits to the right.
