Cylinder Volume Formula :

If π = 3.14 :
V = πr²h
V = 3.14 × 6² × 14
V = 3.14 × 36 × 14
V = <u>1582.56</u><u> </u><u>cm³</u>
If π =
:
V = πr²h
V =
× 6² × 
V = 22 × 36 × 2
V = <u>1</u><u>5</u><u>8</u><u>4</u><u> </u><u>cm³</u>

∠P=∠R, ∠Q=2∠R
the three angles make a total of 180, so
∠P+∠R+∠Q=180
∠R+∠R+2∠R=180
∠R=45
∠P=45, ∠Q=90
Rounded off to the nearest full number, it would be 3 rounds but that wouldn't make sense because 3 x 10 is 30 sooooo the answer would be 3.5 meaning you paid 1 fifth the price of 10 rounds.
