S=4.4П

Answer 2

Calculating the Circumference and Area of a Circle

To calculate the circumference and area of a circle, we can use the following formulas:

1. Circumference (C): - The formula for the circumference of a circle is: C = 2 * π * R, where π (pi) is approximately 3.14 and R is the radius of the circle.

2. Area (A): - The formula for the area of a circle is: A = π * R^2, where π (pi) is approximately 3.14 and R is the radius of the circle.

Given that P = 3.14 and R = 2.2 cm, we can calculate the circumference and area of the circle.

Calculations

1. Circumference (C): - Using the formula C = 2 * π * R: - C = 2 * 3.14 * 2.2 - C ≈ 13.82 cm

2. Area (A): - Using the formula A = π * R^2: - A = 3.14 * (2.2)^2 - A ≈ 15.21 cm^2

Therefore, the circumference of the circle is approximately 13.82 cm and the area of the circle is approximately 15.21 cm^2.
