Answer:
C: 7π metersA:
12.25π meters squared
Step-by-step explanation:
Circumference: dπ or 2πr (d is the diameter and r is the radius, which is half the diameter)
Area: πr2
Circumference: 7π meters (if you use an approximation such as 3.14 for π, multiply that by 7)
Area: (72)2π
Area: 12.25π meters squared (if you use an approximation such as 3.14 for π, multiply that by 12.25)
