what is the areas of a circular region whose diameter is 6cm

Answer 1

The area of a circular region can be calculated using the formula A = πr^2, where A is the area and r is the radius of the circle.

Since the diameter of the circle is 6 cm, the radius would be half of the diameter, which is 3 cm.

Plugging in the radius into the formula, we get:

A = π * (3 cm)^2
A = π * 9 cm^2
A = 28.27 cm^2

Therefore, the area of the circular region with a diameter of 6 cm is approximately 28.27 cm^2.
