To answer such problem, we first need to know the Formula for finding a circle's area, which is "A = πr²".
In the given formula, it is stated that a circle's area is
equal to it's radius, squared then multiplied to π which has an approximate quantity of 3.14. Because the circle's area is already given in this problem, we need to work backwards to find the circle's diameter by using our Formula. Well, if the area of the circle is 153.86 square meters, then dividing 153.86 by the quantity of π (3.14) must give us our radius squared (squared means multiplied by itself ones), and since we get 49 as our quotient (the amount we get from dividing a number by a specific number), that means 49 is our radius squared, now, Identifying the square root of 49 must certainly give us our radius, which is 7.
And finally, because we know that a circle's diameter is double it's radius, we simply multiply 7 by 2 giving us 14 meters as our answer.
To prove my answer, We can use our formula "A = πr²",
So if our diameter is 14 meters, then half of it, 7, must be our radius, then, by multiplying 7 by 7 we get 49 which is 7² (7 squared), we now multiply 49 by 3.14 to get 153.86 meters², the are of the circle.
The whole process I made to identify the circle's diameter is "153.86 ÷ 3.14 = 49, √49 = r, r(2) = d" I hope I helped.
