A triangle was cut out of a square which was originally cut out of a circle.if the diameter of circle was 4cms, the area of triangle is at the most?

• (1/2)*2*4 = 4
  height will be radius of circle
  base will be diam

• 4
  area of circle = 4 pi
  from Pythagoras. 2.x^2=(4^2)=16
  so x = sqrt(8)
  so triangle area = .5 *sqrt(8)*sqrt(8)=4

• Firstly, Consider a Circle
  Now Draw a square. Since All angles are 90. Therefore, diagonal must be passing through the center.(Circle Property)
  Here, we can get the side of square as 2 root 2.
  Now, Since Triangle is taken out from this square. It will give the maximum area when we divide the square in two halves.
  Therefore, area of triangle is 4(Maximum)

• As diameter of circle is 4cm.so this will be the diagonal length of square.
  now,Area of square = 1/2*(diagonal)^2 =1/2*(4)^2 = 8 cm^2.
  since,any square consists of 2 large triangle of equal area.
  so Area of square= 2*Area of triangle
  so,Area of triangle=4 cm^2.

• is it 154

• 1/2*4*2 because we asume base is a diameter
• 11 years agoHelpfull: Yes(0) No(3)
• it must be 4 because the largest traingle possible is as base diameter and height as radius so .5*4*2=4 cmsq

• diagonal of square = 4, side of square= s = 4/sqrt(2)
  area of largest triangle = 1/2*s*s = 0.5*4*4/2 = 4

• it is said...at most...so why not 2*(1/2)*2*4 ?? 8 shud be the answer i guess...

• ans=4 sq cms
• 11 years agoHelpfull: Yes(0) No(0)
• 4 will be the answer !!!

• Ans=4
  Given diameter=4cms
  by we considering the diameter as diagonal for a square,we have two trangles,
  so now area of triangle=1/2bh=1/2(4*2)=4
  here base is diameter of circle or diagonal of square i.e.,4 cms

• b(1/2)*2*4 = 4
  height will be radius of circle
  base will be diam
