1. The area of a circle is calculated by the formula S = nR2, where R is the radius. Knowing the area, we find the radius:
50.24 = 3.14 * R ^ 2;
R ^ 2 = 50.24 / 3.14;
R = √16;
R = 4 (cm).
2. Find the diameter:
D = 2 * R = 2 * 4 = 8 (cm).
Answer: the radius of the circle is 4 cm and the diameter is 8 cm.
