I need help please! my test is almost over in 15 min help!!!!!!!!!!!!

Answer:
The radius is 7
The diameter is 14
The circumference is 43.98 (if they want it simplified put 44)
Step-by-step explanation:
1.The radius is already given in the picture so the answer is 7
2.To find the diameter, multiply the radius by two. 7 times 2=14
3.The formula for circumference is C=2[tex]\pi[/tex]r. Remove the r and replace it with the number 7. Plug 2[tex]\pi[/tex]7 into your calculator and you will get 43.98
