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 cm^2. 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 cm^2.

area of circle is 220 => radius = 70^1/2=> diameter = 280^½ 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.

Gowtham

area of a circle = 220

π r^{2 = 220}

r² = 220/π

r² = 70.

diameter = 2r

d²= (2r)²

d² = 4 * r²

d² = 4 * 70 = 280

area of circle = ½ * d² = 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

π r^{2 = 220}

r² = 220/π

r² = 70.

diameter = 2r

d²= (2r)²

d² = 4 * r²

d² = 4 * 70 = 280

area of circle = ½ * d² = 280/2 = 140 .

Area of circle = 220

πr²=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.
