There would be three main differences, firstly a 9 iron has around 42 degrees of loft, therefore the ball will have a higher launch angle which will make it go higher. The 3 iron has about 21 degrees of loft, and therefore a lower launch angle, and the ball will go much further than the 9. The second difference would be the length of the shaft, the 9 iron shaft can be about 3 inches shorter than the 3 iron. In theory the longer the shaft, for greater the distance from the pivot, which would be your hands so the ball should go further. The 9 iron shaft allows for a better angle of attack, and allows you to compress the ball, and generate spin which is what you want. Also the shorter shaft is designed to give you more control. The final difference is that a 9 irons has bounce, about 8-10 degrees, this prevents the club from digging at impact. The 3 iron would have negative bounce maybe a couple of degrees.
The clubs are lofted differently. Loft refers to the backward slant of the face of a golf club. The greater the loft, the higher the arc of the shot it produces and the shorter the distance. The three iron is designed for a distance of about 190 yards. (Actual distances vary depending upon the skill of the player.) A four iron is good for 180 yards, etc. So, the nine iron is good for shots of about 130 yards.
Three is a factor of nine.
You can make three different groups of three out of nine. 9/3=3
Nine.
9 has three factors.
Four hundred and twenty three billion, ninety million, seven hundred and nine thousand
three is prime nine equals three times three
84
Three point five nine OR three point fifty nine OR three and fifty nine hundredths.
Nine.
You could write it in at least two different ways: twelve and thirty nine thousandths, or twelve point zero three nine.
