Answer:
C= 22[tex]\pi[/tex] A= 121[tex]\pi[/tex]
Step-by-step explanation:
formulas: circumference: 2[tex]\pi[/tex]r area: [tex]\pi[/tex][tex]r^{2}[/tex] diameter = 2r
22/2 = 11, so r = 11
circumference: 2[tex]\pi[/tex]r = [tex]\pi[/tex] * 2r -> 22[tex]\pi[/tex]
area: [tex]\pi[/tex][tex]r^{2}[/tex] = [tex]\pi[/tex] * [tex]11^{2}[/tex] -> 121[tex]\pi[/tex]
