Answer:
310339.1 in^3
Step-by-step explanation:
Volume=4/3*pi*r^3
Volume=4/3*pi*42^3
Volume=4/3*pi*74088
Volume=98784*pi
Volume=310339.0887
So the volume is about 310339.1 in^3
200+12m= 644
subtract 200 from both sides
12m= 444
divide both sides by 12
m= 37
he sold 37 albums
10*30=300
10*4=40
6*30=180
6*4=24
add them up: 300+40+180+24=544
