What is the formula of area of a rod in length and radius?
The formula for the area of a rod, which is a cylinder, is given by A = 2πrh + 2πr^2, where A is the total surface area, r is the radius of the rod, and h is the length of the rod. The first term 2πrh represents the lateral surface area of the cylinder, which is the curved surface area, and the second term 2πr^2 represents the area of the two circular bases of the cylinder. By summing these two terms, we obtain the total surface area of the rod.

a fission rod (fishing rod)
How long must the brace be on a closet rod holder if the vertical side is 7 cm and the horizontal side must be attached 30 cm from the wall?
Pythagoras! length = sqrt (7 squared + 30 squared) ie sqrt 949 ie 30.81 cm
Why is aluminum difficult to weld?
Aluminum is a bit more difficult to weld than steel , because of it's lower melting point. Also Aluminum takes more heat , because of it's property of absorbing and releasing the heat quicker. With the proper electrode , or rod , and amps to volt settings, along with a bit of practise , it can be quite simple . One usually has to have a faster travel speed with the filler rod or electrode.
