The answer would be 28.26.
The reason this would be the answer is because radius is half of a circle and diameter goes through the entire circle the formula for this problem would be
Circumference= 
and the tent has radius of 3m which means we have to multiple 3 × 3 to get 9m and then we would multiply 9 × 3.14 = 28.26

Answer:
Add all the numbers together and u will get your answer
Step-by-step explanation:
The square of a positive integer added to 4 times the integer is 437..
x2 + 4x = 437
I chose to do this by completing the square..
x2+4x+4 = 437 + 4
(x+2)2 = 441
Take square root of both sides
x+2 = ±√441
x = -2 ± 21
x = -23 or x = 19
x = 19
