Question

if the area of square inscribed in a circle with the radius 70 cm is?

plz help me fast ​

Answer 1

Answer:

Radius = 70cm.

Diameter = 2 × Radius = 70×2 = 140cm.

Lets draw the figure.

We know that If a square is inscribed in a circle then the diameter of the circle must be diagonal of the square.

Thus, we can conclude that diagonal = diameter.

Thus, diagonal of square = 140 cm.

Now, we know that Side of a square = diagonal ÷ √2

= 140 ÷ √2

= (140×√2)÷(√2×√2)

=(140√2)÷2

=70√2cm.

Area of square = side²

=(70√2)²

=9800 cm².
