प्रश्न
The curved surface area of a right circular cylinder of height 14 cm is 88 cm2. Find the diameter of the base of the cylinder.
Assume `pi = 22/7`
उत्तर
Height (h) of cylinder = 14 cm
Let the diameter of the cylinder be d.
Curved surface area of cylinder = 88 cm2
⇒ 2πrh = 88 cm2 (r is the radius of the base of the cylinder)
⇒ πdh = 88 cm2 (d = 2r)
`rArr22/7xxd xx14cm = 88" cm"^2`
⇒ d = 2 cm
Therefore, the diameter of the base of the cylinder is 2 cm.
