Answer:
Circumference = 74.2924 inches.
Step-by-step explanation:
Given : area = 437.4 in².
To find : Find the circumference .
Solution : We have given area = 437.4 in².
Area = π (radius)².
π (radius)² = 437.4 in².
3.14 (radius)² = 437.4 in².
On dividing both sides by 3.14
(Radius)² = .
(Radius)² = 139.299.
On taking square root both sides
Radius = 11. 83 inches
Circumference = 2 * π * radius .
Plug the values
Circumference = 2 * 3.14 * 11.83 .
Circumference = 74.2924 inches.
Therefore, Circumference = 74.2924 inches.
