Help, my teacher told me its wrong

Need ! discuss how to convert the standard form of the equation of a circle to the general form. 50 points

The magnitude, m, of an earthquake is defined to be m=log l/s, where i is the intensity of the earthquake (measured by the amplitude of the seismograph wave) and s is the intensity of a “standard” earthquake, which is barely detectable. what is the magnitude of an earthquake that is 1,000 times more intense than a standard earthquake? use a calculator. round your answer to the nearest tenth.

Choose the more precise measurement. 26.4 cm or 8.39 cm
