Answer 1

Радиус круга(S)=r*r*пи
S=3,6*3,6*3,14=40,715
длина окружности=2*пи*r
длина окружности=3,6*2*3,14=22,608

Answer 2

Calculation of Circle Area and Circumference

To find the area and circumference of a circle, we need to know its radius. In this case, the radius of the circle is given as 3.6.

The formula for the area of a circle is A = πr^2, where A represents the area and r represents the radius.

The formula for the circumference of a circle is C = 2πr, where C represents the circumference and r represents the radius.

Let's calculate the area and circumference of the circle with a radius of 3.6.

1. Calculation of Area:

Using the formula A = πr^2, we can substitute the value of the radius (r = 3.6) into the formula:

A = π(3.6)^2

Calculating the value:

A = 40.694

Therefore, the area of the circle with a radius of 3.6 is approximately 40.694 square units.

2. Calculation of Circumference:

Using the formula C = 2πr, we can substitute the value of the radius (r = 3.6) into the formula:

C = 2π(3.6)

Calculating the value:

C = 22.619

Therefore, the circumference of the circle with a radius of 3.6 is approximately 22.619 units.

Please note that the values provided are approximate due to rounding.
