Since, observer is taken the weight of men over age 18. Thus, it is good sample which represent whole population.
Answer: Area of a right circular Cylinder--- curved surface area -2πrh Total surface area -2πr(r+h),where 'r' is the radius of the circular surface and 'h' is the height of the cylinder.
The word "tri" means 3, so a trinomial has 3 terms. For example, 2x^2+3x-4
Two consecutive odd numbers with the sum of 144 is 71+73
