a cylindrical pipe is 2.8 m long its intenal radius is 3.5 and its external radius is 5cm calculate. a.the volume of water in litres that the pipe can hold when full. corrext to 1 dp taking π= 22/7.b. the volume of water in cm of the metal used in making the pipe​

step-by-step explanation: noo

x coordinate can be written by using the formula, x= x1 + 2/5(x2 - x1)

step-by-step explanation:

formula

x = x1 + p/w(x2 - x1)

let the line segment ab with a(x1,y1) and b(x2,y2)

a point(x,y) divide ab in the ratio, 2: 3 the x coordinate can be written as

x = x1 + p/w(x2 - x1)

here p=2 and w = 2+3

therefore,

x coordinate can be written by using the formula, x= x1 + 2/5(x2 - x1)

similarly y coordinate y = y1 + 2/5(y2 - y1)
