Question

If the area of the circle is 314 m2 , then it's diameter is _____ (use pie = 3.14)​

Answer 1

We can derive the diameter of a circle formula using the area of the circle formula that is:

area = π(Radius) x 2

Hence, the diameter of the circle formula using area, D = 2√Area/π.

Diameter = 2 x √314/3.14

= 2 x 17.7/3.14

We'll round 17.7 to 18 as it is more simple to calculate.

= 2 x 18/3.14

= 2 x 5.7

Here too, we'll round 5.7 to 6

= 2 x 6

= 12

Diameter = 12m

Answer 2

Answer:

The diameter of the circle is 20 m.

Step-by-step explanation:

Area of Circle = πr² or $\frac{\pi d^2}{4}$, square units

         where π = 3.14

Given, the area of the circle is 314 m²

                             $\frac{\pi d^2}{4} =314\\ \\ d^2=\frac{314 \cdot 4}{3.14} \\ \\ d^2=400\\ \\ d=20 m$
