Sorry There"s A Mistake. Let The External Radius Be "R" And Internal Radius Be "r". Volume Of Hollow Pipe = Pie* (R 2 -r 2 )*h. Internal Radius = External Radius- Thickness. R = 8/2 = 4. r =4-1 = 3. R 2 -r 2 = 4 2 -3 2 = 7. h = 21m = 2100 cm. =>22/7*7*2100 = 46200 cm3.An iron pipe 20 cm long has exterior diameter equal to 25 A hollow iron pipe is 21 cm long and its external diameterAn iron pipe 20 cm long has exterior diameter equal to 25 cm.if the thickness of the pipe is 1 cm,find the whole surface area of the pipe. 2 A hollow iron pipe is 21 cm long and its external diameter Height of pipe = 20 cm External diameter = 25 cm A hollow iron pipe is 21 cm long and its external diameter (21.8Refer to paragraph 3The expression tech wizard' meansChoose the correct answer to complete the following sentence,0000>completely ignorant A hollow iron pipe is 21 cm long and its external diameterArea of Hollow Cylinder - Curved and Total Surface Area of A hollow iron pipe is 21 cm long and its external diameterA hollow cylinder copper pipe is 21cm long.
