Answer:
79 units²
Step-by-step explanation:
The area of a circle is found by using the formula A = π x r². Since we are not given the radius we can use the formula r = C / (2π). Substituting in the given values, we get r = 31.5/(2π). 2 times pi is 6.283185307. 31.5 divided by this will get you 5.013380707. Now, put that value in for r in the area equation. A = π x 5.013380707². Pi times 5.013380707² equals 78.96074613. This can be rounded to 79. (Or 80 if you need to the nearest whole number.)

4/6 will simplify to 2/3
9/12 will simplify to 3/4
Find a common denominator
12 is a good one
8/12
9/12
9/12 is greater than 4/6
The probability of the student picked will be a junior is 27 percent.
there is a total of 30 kids. 8 are juniors. 8/30 = 0.266
move the decimal back two spaces for a percent. 26.6% is your precise answer. after rlunding it wpuld be 27 percent.
hope this helps
