Answer 2

To find the values of S (surface area), C (circumference), and D (diameter) of a circle with a radius of 4 cm, we'll use the following formulas:

1. Surface Area of a Circle (S): S = π * r^2

2. Circumference of a Circle (C): C = 2 * π * r

3. Diameter of a Circle (D): D = 2 * r

Given that the radius (r) is 4 cm, we can now calculate the values:

1. Surface Area (S): S = π * (4 cm)^2 S = π * 16 cm^2 S ≈ 50.27 cm^2

2. Circumference (C): C = 2 * π * 4 cm C ≈ 2 * 3.14159 * 4 cm C ≈ 25.13 cm

3. Diameter (D): D = 2 * 4 cm D = 8 cm

So, the values are approximately: S ≈ 50.27 cm^2 C ≈ 25.13 cm D ≈ 8 cm
