The diameter of Kelly's bicycle tire was 26 inches. What is the circumference of the tire?

see below

Step-by-step explanation:

The circumference of a circle is given by

C = pi * d

C = pi * 26

C = 26pi

We can approximate pi = 3.14

C =81.64 inches

or we can approximate pi by using the pi button

C =81.68140899 inches

Using the choices listed and approximating pi as 3

C = 3*26 = 78 inches

total amount of money that he should pay if he has not used his duty free exemption is $98

step-by-step explanation:

given a united states citizen returning to the states declares the following items at the customs office: 3 shirts at $8.50 each 2 dresses at $27.50 each 1 pair of gold cuff links at $17.50 per pair. we have to find how much he pay

cost of 3 shirts if one cost at $8.50 is

cost of 2 dresses if one cost at $27.50 is  

cost of 1 pair of gold cuff at $17.50

so, total amount of money that he should pay if he has not used his duty free exemption is   $25.5+$55+$17.50=$98
