The volume is 13*7*5. Therefore, the answer is 455 in^3
Volume = 4/3×pi×r^3
= 4/3×3.14×12^3
= 7234.56
~ 7235
Answer: x=40
Step-by-step explanation x-0.3x=28
Add similar elements x-0.3x=0.7x
0.7x=28
Multiply both sides by 10
0.7x · 10= 28 · 10
Refine
7x=280
Divide both sides by 7
Simplify
x = 40
Move the decimal point 4 times to the left
