Answer:
you have to do
92×98=9016
then 9016=10(here we roud to 1 signification figure)
49×138=6762
6762=6
216×876=189216
189216=1

The equation represents the magnitude of an earthquake that is 10 times more intense than a standard earthquake is
.
Given
The magnitude, M, of an earthquake is defined to be M = log StartFraction I Over S EndFraction, 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.
<h3>The magnitude of an earthquake</h3>
The magnitude of an earthquake is a measure of the energy it releases.
For an earthquake with 1,000 times more intense than a standard earthquake.
The equation represents the magnitude of an earthquake that is 10 times more intense than a standard earthquake is;

Hence, the equation represents the magnitude of an earthquake that is 10 times more intense than a standard earthquake is
.

C=2πr and x^2+y^2=r^2
r=4 because of the equation (16)^1/2 is 4
C=8π
