• circumference = 2pye r
• area = pye r2
• 22/731.2531.25= 321.9 , 321.85 , 322 1   #### Larry Thornton

To calculate circumference you can use either of the formula
C = πd or
C =2πr
Where
C = circumference
d = distance
π = 3.14 (constant)
For this question, we will use the second formula
C = 2 3.14 51.25
C = 321.85
Round up to the nearest tenth we have = 321.9    #### John Smith
