In a circle with a circumference of 25.12 cm, draw the largest square, the square area is___ Square centimeter

In a circle with a circumference of 25.12 cm, draw the largest square, the square area is___ Square centimeter

The diagonal of the square: 25.12 △ 3.14 = 8 (CM), the area of the square: 8 × 82 △ 2 × 2 = 32 (square cm); answer: the area of the square is 32 square cm. So the answer is: 32

It is known that the perimeter of a right triangle is 48 cm and the area is 96 square cm

Let a and B be two right angles and C be hypotenuse
a+b+c=48;
ab=192;
a^2+b^2=c^2;
For the first equation, there is
（a+b)^2=(48-c)^2;
Namely
a^2+b^2+2ab=48^2-96c+c^2;
The above formula is combined with a ^ 2 + B ^ 2 = C ^ 2 and ab = 192
c=20；
A + B = 28;
And ab = 192, LIANLI can get it
A = 16, B = 12; or a = 12, B = 16;
