Question

Find the circumference given the area = 437.4 in². Use 3.14 for π as necessary.

Answer 1

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 = $\frac{437.4}{3.14}$.

(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.

Answer 2

the circumference would be around74.1197 but you can round it down depending on the decimal place needed. The math 437.4/3.14= 139.2993630573248 then find the quare root of it =11.80251511574227=r r x 3.14 =37.0598974634374 x 2 = c
