Question

10. Volume of a cylindrical wire of radius 1 cm is 440 cm³. It is cut into three unequal segments. If the lengths of two cut segments are 6 cm and 8 cm, then the length of the third segment is

(a) 252 cm
(b) 126 cm
(c) 120 cm
(d) 240 cm ​

Answer 1

volume of cylinder=440cucm

radius=1cm

segments=6cmand8cm

volume of cylinder=2π1(1+14)

2×22÷7×1(15)

44÷7(15)

44÷7×15
