Question

Q5. The curved surface area of a cylinder is 264

. If the height of the cylinder is increased by 3,its curved

surface area increases to 528

. Find the radius of the cylinder.

​

Answer 1

Answer:

radius is 7

Step-by-step explanation:

curved surface area for cylinder is 2*π*r*h

Given  2*π*r*h= 264     eq(1)

if the height increased by 3 means (h+3)

then curved surface area will become,

         2*π*r*(h+3)= 528    eq(2)

by diving eq(1) by eq (2)

we get h=3

then to find radius

2*22/7*r*3=264

by solving , r=14
