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.
Radius is 8.912
The radius is 1/2 the diameter. So, 56 / 2 = 28 radius.
The area of a circle with a radius of 14.4 is 651.4
Area of a circle = pi*radius squared
