Question:

How many meters is the sealant 3 centimeters thick?

How many meters is the sealant 3 centimeters thick?

Answer:

According to the calculated thickness sealing glue sealing tape length, which is about 150m cm.
3, and then use the arithmetic sequence knowledge obtained tape length:L=2 PI (r+d) +2 PI (r+2d) =.+2 PI (r+nd)=2 PI nr+2 PI D (1+2+ =..+n)=2 PI nr+ PI n (n+1) d=2 PI nr+ PI D[(D/d) +1)
The method and procedure for calculating the length of the adhesive tape are as follows:1. Use vernier caliper to measure the thickness of the tape, D, and the radius of the inner circle of the tape R.
