The sum of radius and height of a cylinder is 16. If
the total surface area of the cylinder is 704 m2
. Then
find the volume of the cylinder.
(1) 1386 m2
(2)1224 m2
(3) 2466 m2
(4) 1804 m2
(5)1454 m2

• ANS=(1).
  let H is the height of cylinder and R is the radius of cylinder.
  given R+H=16.
  total surfacee area of cylinder is 2*^*R*(R+H)=704 given
  Putting the value of R + H we have R=7 and H =9.
  now volume of cylinder is ^*R*R*H=^*7*7*9=1386 m3

• ans-1.
  r+h=16
  and surface area=2*(pie)*r(h+r)=704 (given)
  =2*(22/7)*r*(16)=704 (r+h=16 given)
  = r =(352/16)*(7/22)
  = r =7
  r+h=16 => h=16-7=9 =>h=9
  Volume=(pie) *(r^2)*h
  =22/7 * 7*7 *9
  =22*7*9
  =1386 ans

• surface area=2*3.14*r(r+l)
  704 =2*3.14*r*16
  r=704*7/3.14*2*16
  r=7
  r+l=16
  l=16-7=9
  volume of cylinder=3.14*r*r*l
  =3.14*7*7*9
  =1386

• r+h= 16
  Total surface area of cylinder= 2r(r+h)22/7=
  2r(16)22/7 = 704
  r=7 h=16-r=9
  Volume= r.r.h.22/7= 1386m2
