c = 2пR – formula for the length of a circle. Therefore, you can find the radius
R = s / 2 * p.
S = nR ^ 2 – the formula for the area of a circle.
9.42 / 2 * 3.14 = 1.5 (cm) – radius of the circle.
3.14 * 1.5 ^ 2 = 7.065 (cm ^ 2) – the area of a circle bounded by this circle.
Answer: 7.065 cm ^ 2 is the area of a circle.
