area of the circle is 220 means  3.14*r2 . then area o fthe square is area of the circle divided by 3.14. that means area of the square is 70.

the answer is 140 cm2. From the area of the circle will get the value of r.after that find the value of the diameter of the circle i.e 2r.But  if we see for the square  the diameter is the length of the diagonal of the square i.e 2r=sq .root 2a(a= side of the square).and from here we will get a2=140 cm2.

area of circle is 220 => radius = 701/2   => diameter = 280½        diagonal of square =  >  area = [280{1/2}2]/2  =>  140

Area of a circle = 220=> Πr² = 220=> 22/7 r² = 220=> 1/7 r² = 10=> r² = 10×7=> r² = 70=> r = √70.We know, diameter = 2×radiusTherefore, diameter = 2×√70Now, area of square = 1/2× (diagonal) ² =1/2×2×√70×2×√70 =(√70)² × 2 = 70 × 2 = 140.Therefore, the area of square is 140cm².

area of a circle = 220
π r2 = 220
r = 220/π
r = 70.
diameter = 2r
d= (2r)2
d = 4 * r2
d = 4 * 70 = 280
area of circle = ½ * d = 280/2 = 140 .

Area of a circle = 220=> Πr² = 220=> 22/7 r² = 220=> 1/7 r² = 10=> r² = 10×7=> r² = 70=> r = √70. If we let the square is ABCD and the centre is O then from triangle AOB we get AB²= OA² + OB² =(√70)² +(√70)² = 70 +70 AB² =140 AB = √140Therefore the area of the square ABCD= AB× AB= √140 × √140= 140 cm²

= 280/2 = 140 . a2a= d2/2we know that in square, area  = 70. diameter d=2r  d2=(2r)2d2=4r2d2=4x70=280rπ = 220/r= 220  r πArea of a circle

π r2 = 220
r = 220/π
r = 70.
diameter = 2r
d= (2r)2
d = 4 * r2
d = 4 * 70 = 280
area of circle = ½ * d = 280/2 = 140 .

Area of circle = 220
πr=220
r2=220/π   put π=22/7
r2=70
r=√70
diameter, ,d = 2r = diagonal of square
d=2√70
Area of square=1/2×d2
=1/3 × 4 ×70
= 140

DEAR FRIEND
Area of the circle = 220 cm. sq. The radius of the circle is half the diagonal of the square. Therefore, Area of the square whose vertices are on the circle= 140 cm².
THANK U
