Yes your answer can be one number
Answer: 32π
Decimal: 100.53 (Not rounded)
Formula for a Cone: ⅓ πr^2h.
20=3x-1
move -1 to the other side
sign changes from -1 to +1
20+1=3x-1+1
20+1=3x
21=3x
divide both sides by 3 to get x by itself
21/3=3/3x
Cross out 3 and 3, divide by 3 and then becomes 1*1*x=x
21/3=x
Answer:
x=7
