What is the diameter of a circle if the area is 56?

Answer 1

To find the diameter of a circle when given the area, we first need to calculate the radius. The formula for the area of a circle is A = πr^2, where A is the area and r is the radius. Given that the area is 56, we can rearrange the formula to solve for the radius: r = √(A/π) = √(56/π) ≈ 4.74. Finally, to find the diameter, we double the radius, so the diameter of the circle is approximately 9.48 units.

Answer 2

diameter = 2 × radius

Area_circle = π × radius²

→ radius = √(area_circle ÷ π)

→ diameter = 2 × √(area_circle ÷ π) = 2 × √(56 units² ÷ π) ≈ 8.444 units.
