What is the radius, in centimeters, of a circle that has a circumference of 16π?
8
16
32
64
Answer: The radius equals 8cm
Answer:
8
Step-by-step explanation:
The circumference of a circle is equal to π , which is a number ≈ 3.14 , multiplied by the diameter of the circle.
Therefore, C = π d .
We know that the circumference, C , is 16 π , so we can say that:
16 π = π d
We can divide both sides by π to see that 16 = d .
We now know that the diameter of the circle is 16 .
We also know that the diameter has twice the length of the radius.
In equation form: 2 r = d
2 r = 16
r = 8
Note that since 2 r = d , the equation C = 2 π r holds and can be used in place of C = π d .

Children get a 15% discount on tickets to an amusement park. Jun had a coupon for 5% off any two tickets. He used the coupon for himself and his 4-year-old son, Jack. If regular admission for a ticket was $60, what did Jun pay for the two tickets?
The amount that Jun paid for the two tickets given the discount rate and the coupon rates is $105.45.
How much was paid for the two tickets?Discounts and coupons reduce the price of an item.
Cost of the child's ticket after the discount = (100 - 15%) x 60 = $51
Cost of both tickets after the coupon = (100 - 5) x (51 + 60) = $105.45

Coach Cliffman made a deposit of $1,800 into an account that earns 2% annual compound interest. Find the amount of interest that Coach Cliffman earned after 3years.
Answer: 5508$
Step-by-step explanation:
So to find interest your formula is this:
Int=interest rate (percent)*principal
So your problem would be: int=.02*1800
This equals 36. Since its interest, you add your interest (36) and your principal (1800) and get 1836. Now, since you need to find the interest for 3 years, you multiply 1836 by 3.
Step-by-step explanation:
