Well.
The relation between the circumference of a circle and its diameter is described by the following equation: Thecircumference=\pi d
where d is the diameter of the circle.
For a giving diameter (d=3ft), we can substitute in the previous equation 
The circumference of a circule= 3.14*3 (you can use ur calculator to find the exact number i guess it will be about 9.42 ft)

I hope it helps.

Which of the following are true if you pay only the minimum amount each month towards your credit card bill? AYou will be charge
faust18 [17]

Answer:

A- You will be charged interest on your remaining balance.

C- You may be in debt for a long time.

Step-by-step explanation:

The following are true if you pay only the minimum amount each month towards your credit card bill:

Firstly one will be charged interest on the remaining amount. Suppose you had a bill of $500. But you paid the minimum of $100. So, you will be charged your standard interest rate on $400.

And with this format, one will be in a debt for a long time as each month some new balance will be added to the previous one.

So, options A and C are true.

B is not true as the interest rates are not changed during the cycle.

Whats the mean for this data? round to 2 decimals places
kolbaska11 [484]

Answer:

1992.38

Step-by-step explanation:

The mean, or average, of a set of data points is found by adding all the values together and dividing by the number of values.

Sum:

1911.56 + 1956.69 + 1903.16 + 1958.82 + 1910.87 + 1983.14 + 2014.12 + 2023.86 + 2057.26 + 2034.21 + 2087.73 + 2067.14 = 23908.56

Divide:

There are 12 numbers, so divide 23908.56 by 12:

23908.56 / 12 = 1992.38

The average is thus 1992.38.
