15%

Step-by-step explanation:

You take the number of student in 8th grade that are on social media for more than an hour which gives you (12) and divide it by the total number of students (81).

12/81=0.148 repeating

You then round 0.148 repeating to 0.15 and then turn it into a percent by moving the decimal two places to the right.

1/3

Step-by-step explanation:

For the first circle 2 x 2in = 4 to find diameter

4 x 3.14 = 12.56

6in x 2 = 12

12 x 3.14 = 37.68

simplify

12.56/37.68

6.28/18.84

3.14/9.42

So the answer is 1/3 since 3.14 x 3 = 9.42

Also since the radius is 3 times longer
