PLEASE HELP !! EXPLAIN WITH STEPS The magnitude, M, of an earthquake is represented by the equation M=2/3log (E/E0) where E is the amount of energy released by the earthquake in joules and E0=10^4.4 is the assigned minimal measure released by an earthquake.
To the nearest tenth, what would be the magnitude of an earthquake releasing 2.1⋅ 10^14 joules of energy?

4.5*10^12

Step-by-step explanation:

5.5=2/3log(E/10^4.4)

8.25=log(E10^4.4)

10^8.25=E/10^4.4

E=10^4.4*10^8.25

E=10^12*4.5

80π/3 or about 83.775

step-by-step explanation:

since a cone is 1/3 of a cylinder, we need to find the base's area. since area = πr^2, we get 16π. then, multiplying this by 5, we get 80π. dividing by 3, since the cone's volume is 1/3 of that of a cylinder's, we get 80π/3.

hope this !
