The Equation you are going to use: P(event)=number of favorable outcomes/total number of possible outcomes

1. Equal to
The probability of rolling a 4 is 1/6. There is 1 favorable outcome and 6 possible outcomes. The frequency of rolling a 4 after 90 times is 15/90 which is equal to 1/6. Therefore equal to.

2. Greater than
The probability of rolling a number less than 4 is 3/6 or 1/2. After 90 times, the outcome was 46/90 which simplified is 23/45. Half of 45 is 22.5 and 23 > 22.5.

3. Less than
The probability of rolling a multiple of 3 is 2/6 or 1/3. After rolling the cube 90 times, the outcome was 24/90 which simplified is 4/15. 1/3 of 15 is 5. 4 < 5. Therefore, less than.

A circle has a circumference of 16π yards. Find the area in terms of π (pi).

Answers

64 pi. Since the formula for the circumference of a cirlcle is: pi x diameter. The diameter of the circle would be 16. And the radius of that would be 8 since its half of 16. The formula to find the area is: pi x radius squared. So 8 squared pi would be 64 pi.

64 pi is the answer if I’m correct
