Answer:
im not sure if it right or not because im stupid but i guess 6.5
Step-by-step explanation:
Solve for x by cross multiplying
Exact form: x= 191/7
Decimal form :x=27.28571428
Mixed number form:x=27 2/7
Answer:
14π cm
Step-by-step explanation:
Circumference of a circle given the diameter is :
πd
We simply substitute the value given in the image into our formula to find our answer:
πd = π×14 = 14π
Units will be cm as circumference is a length
This is our final answer as the question states to leave it in pi form .
