Question

R=3см С? S? Сроснооо

Answer 1

С=18,84см
S=28,26cм^2

Answer 2

It seems like you're asking about the properties of a circle with a radius of 3 centimeters (R=3cm). Let me provide you with some information:

1. Circumference (C): The circumference of a circle can be calculated using the formula C = 2πR, where R is the radius. In your case, with R=3cm:

   C = 2π(3cm) ≈ 18.85 cm (rounded to two decimal places)

2. Area (S): The area of a circle can be calculated using the formula S = πR^2, where R is the radius. In your case:

   S = π(3cm)^2 ≈ 28.27 square centimeters (rounded to two decimal places)

So, for a circle with a radius of 3 centimeters, the circumference is approximately 18.85 centimeters, and the area is approximately 28.27 square centimeters.
