Question

R = 3,6 см, C - ? S - ?

Answer 1

Відповідь:

С=38 см

S=113 см²

Покрокове пояснення:

R = 3,6 см

C - ?

S - ?

С = 2πR

C= 2·3,14 ·6 = 37,68 см = 38 см

S круга = πR²

S= 3,14 ·(6·6) = 3,14·36 = 113,04 ≈ 113 см²

Answer 2

To find the circumference (C) and the area (S) of a circle, you need to know the radius (R).

Given that the radius (R) is 3.6 cm, we can calculate the circumference (C) and the area (S) using the following formulas:

Circumference (C) = 2πR Area (S) = πR^2

Substituting the value of the radius into the formulas:

C = 2π(3.6) ≈ 22.62 cm (rounded to two decimal places) S = π(3.6)^2 ≈ 40.69 cm^2 (rounded to two decimal places)

Therefore, the circumference (C) is approximately 22.62 cm, and the area (S) is approximately 40.69 cm^2.
