Calculate the radius (half the diameter), then use the formula area = pi x radius2. Alternately, you can use the formula area = (1/4) x pi x diameter2.

The area of a circle 4.6m in diameter is 16.62 square meters.
A=πr²The diameter is 12. so the radius (r) is 6A= 3.14159 X 6²A= 3.14159 X 36A= 113.1 m²
3,848.45 square meters.
Area = pi*14.452 = 655.972 square m to 3 dp
24 meters.The diameter is twice the radius.Both radius and diameter are straight lines. The radius extends from the center of the circle to any point on the circumference. The diameter extends from any point on the circumference through the center to the circumference on the opposite side of the circle.
