The formula given to us relates circumference with radius but we are given diameter instead. good thing we know that diameter is twice the length of radius so if diameter=28, the radius=14. therefore, using our formula, we can find the circumference:
C = 2(pi)(14)
C = 87.96
and this answer is close to 88 so the answer is A
let me know if you have any questions!!!
Multiply each side by 6 to get rid of the fraction. 96/2 = 48
Answer:
You need to add an attachment or type the answer choices.
Step-by-step explanation:
It's A because if you divide any number of hours and it's corresponding distance from data table shown in A by a number to get one hour you get a distance of 25 kilometers, for example ; 2 hours and 50 kilometers, divide it by 2 to get 1 hour and 25 kilometers. Or 6 hours and 150 kilometers divided by 6 to get 1 hour and 25 kilometers Therefore it is 25 kilometers per hour .
