What is the area of a circle 3.102cm3.102cm in diameter?

The area of a circle is calculated using the formula: Area = πr², where r is the radius of the circle.

Step 1: The diameter of the circle is given as 3.102 cm. The radius is half of the diameter, so we divide the diameter by 2 to get the radius.

r = Diameter/2 = 3.102 cm / 2 = 1.551 cm

Step 2: Substitute the radius into the formula for the area of a circle.

Area = πr² = π * (1.551 cm)²

Step 3: Calculate the area.

Area = 3.14159 * (1.551 cm)² = 7.52 cm²

So, the area of the circle is approximately 7.52 cm².
