Answer:
A equals 254.46
C equals 56.54
Step-by-step explanation:
Area
pie (3.14) times the radius (9) times ^2 is equal to
254.46
Circumference
(2) times pi (3.14) times radius of (9) to get
56.54
Area of a circle formula = [tex]\pi[/tex]r² where r means radius and [tex]\pi[/tex] means 3.14
3.14(9)^2 = 254.34 = area
Circumference formula: 2[tex]\pi[/tex]r
2(3.14)(9) = 56.52 = circumference
