★ Appropriate Question :

  • If the volume of an cylinder is 700 cubic CENTIMETERS and the area of the base is 100 square centimeters, what is the LENGTH of the cylinder?*

  • 1). 70 cm
  • 2). 7 cm ✔
  • 3). 700 cm
  • 4). 7 sqcm

★ Required Solution :

★ Values given to US :

  • ➻ Volume of cylinder = 700cm³

  • ➻ Area of base of cylinder = 100cm²

★ Formula used here :

  • ➻ area of base of cylinder = πr²

  • ➻ Volume of cylinder = πr²h

✴ Let ‘h’ be length of cylinder

★ According to question :

  • ➻ Volume of cylinder = area of base of cylinder

  • ➻ 700cm³ = 100h

  • ➻ 700 / 100 = ‘h’

  • ★ value of height = 7 cm ★

THEREFORE :

OPTION (2) is correct ✔ ✰
