iF the diameter of the circle is increased by 33% then what will be the circumference of the circle?

• C1 = pi*d
  C2 = pi*[d+(d*33/100)] = pi*1.33*d
  C2/C1=(pi*1.33*d)/(pi*d)
  C2/C1=1.33
  C2=1.33*C1
  circumference of the new circle will be 1.33 times of old circle

• Let diameter of the circle be x therfore the circumference = 3.14*x
  Now if the diameter is increased by 33% it will become 1.33*x then circumference will be 3.14*1.33*x = 4.1762*x

• if it is increased by 33% then it will be 10.362 more then before .
  ans: 10.362
  let 10 be the dia.
  circumfr=2*3.14*(10/2)=31.4
  now increased by 33% dia will be 13.3
  circumfr=2*3.14*(13.3/2)=41.762
  hence the difference will be = 10.362 .

• circumference=2*3.14*r
  therefore-radius=33/100
  then,c=2*3.14*0.33=2.0724

• circumference of circle=3.14*d
  let diameter is 100
  33%increase then newdiameter=133*d/100
  newcircumference=3.14*133d
  =4.17

• let the original diameter be 'd'. So after increasing 33% the diameter will be 'd+33%of d'=133d/100. so the circumference will be 'pi*133d/100'.

• If d was the original diameter, then
  new diameter D = d+(33*d/100) = (133*d)/100
  hence new radius R= D/2 = (133*d)/200
  then circumference will be, C = 2*3.14*R = (133*3.14*D)/100

• let the original dia be d
  now,after increasing 33%, new dia =1.33d
  so, radius=1.33d/2
  therefore, circumference =2*3.14*1.33d/2=4.17d
• 11 years agoHelpfull: Yes(0) No(0)
• diameter of circle=x (say)
  new diameter=x*133/100
  so radius=x*133/200
  since circumference of circle=2*3.14*radius
  so answer=2*3.14*133/200=2.09

• D+.33D is new diameter so circumference is piXD so new circumference is 1.33 x pi x D

• C1 = pi*d
  C2 = pi*[d+(d*33/100)] = pi*1.33*d
  C2/C1=(pi*1.33*d)/(pi*d)
  C2/C1=1.33
  C2=1.33*C1
  Circumference of the new circle will be 1.33 times of old circle
  
  Answer: 1.33

• dia of 1st circle d
  circum c1 = pi*d
  inc by 33% ==> (1+.33)d ==> 1.33d
  then c2 = 1.33d * Pi
  therfore circumference of new circle will be 1.33 times old circle since 1.33d*pi/Pi*d = 1.33
