Question

R=4см найти C и S !!!!!!!!!!!!!!

Answer 1

с=2πR=2π*4=8π (cм)

S=πR²=π*16=16π(см²)

Answer 2

Finding the Area and Circumference of a Circle

To find the circumference (C) and the area (S) of a circle with a radius of 4 cm, we can use the following formulas:

Circumference (C): The formula for the circumference of a circle is given by: C = 2πr

Area (S): The formula for the area of a circle is given by: S = πr^2

Now, let's calculate the circumference and area using the given radius of 4 cm.

Calculations

Circumference (C): Using the formula C = 2πr: C = 2 * 3.14 * 4 C = 25.12 cm Area (S): Using the formula S = πr^2: S = 3.14 * (4)^2 S = 3.14 * 16 S = 50.24 cm^2 Therefore, for a circle with a radius of 4 cm: - Circumference (C) = 25.12 cm - Area (S) = 50.24 cm^2
