Moon's diameter - 358 px - 3474.2 km
Radius of the Moon - 179 px - 1737.1 km
Diameter of the crater - 134 px - 1300.40 km
Distance from the middle of the Moon to its shadow - 146 px
The angle of the Sun: (0.5pi)-asin(146/179) = 0.617 rad
Distance between the axis of the Moon and the edge of the crater - 7 px
The angle: asin(7/144) = 0.048 rad
Total angle: 0.617+0.048 = 0.665 rad
Shadow - 78 px - 756.95 km
Height - 756.95*tan0.656 = 593.56 km
I don't know how to solve the problem above using geometry so I'm going to make a drawing
Outer radius of the crater - 71 px - 689.02 km
Depth of the crater - 53 px - 629.17 km
Volume: (pi*629.17^2/3)*(3*689.02-629.17) = 596060433 km^3 or 596060433*100000^3 cm^3
V. frag = 69*596060433*100000^3 = 4.11*10^25 Jouls - 9.82 Petatons (Multi-Continent level)
Method 2[]
Since all the debris starts orbiting around I'm going to calculate KE using escape velocity of the Moon
The average density of the Moon - 3.34 g/cm^3
Mass: 3.34*596060433*100000^3 = 1.99e24 g or 1.99e21 kg
The escape velocity of the moon: 2375 m/s
KE = 0.5*1.99e21*2375^2 = 5.61*10^27 - 1.34 Exatons (Multi-Continent level)
