CIRCUMFERENCE+AREA OF A CIRCLE

The radius is the distance from the center of the circle to any point on its circumference.

The area (A) of a circle is calculated using the formula: A = $$\frac{1}{2} \times \text{diameter} \times \text{height}$$ .

The area of a circle represents the space inside the circle.

The diameter is the distance across the circle, passing through the center, and is twice the radius.

The circumference (C) of a circle is calculated using the formula: C = $$\text{diameter} \times \text{π}$$ or C = $$2 \times \text{radius} \times \text{π}$$ .

The diameter is 24 cm, since diameter = 2 × radius.

The area is 113.04 cm², calculated using A = $$\text{π} \times (6)^2$$ .

The value of π (pi) is approximately 3.14.

A segment that does not connect the center to the circumference is not a radius.

Use the formula: A = $$\frac{1}{4} \times \text{π} \times \text{diameter}^2$$ .
