Question

area of smallest square that can circumscribe a circle of 1386 sq cms

Answer 1

see since the the diameter of the circle will be equal to a side of square le us take lenght of the diameter x

area of a circle is 1386.
araa of circle ➡ (22
➗7)❌(radius)❌(radius).

1386➡(22➗7)❌(radius)^2.

1386❌7➡(22)❌(radius)^2.

9702➗22➡(radius)^2.

441➡(radius)^2.
radius➡21 (441 is a square of 21).

Since,diameter ( x ) is double the radus we will multiply rasius ( 21 ) by 2.

so diameter = 42 cms.

side of a square = 42 cms.

area of a square = side❌side = 42❌42.
= 1,764 square cms.
