What is the approximate area of the circle that fits perfectly inside of the square? use 3.14 and round to the nearest tenth.

You must apply the formula for calculate the area of a circle. The formula is:

 A=πr^2

 Where A is the area, and r is the radius of the circle.

 The radius of the circle is:

 r=5 cm/2
 r=2.5 cm

 When you substitute the values into the formula, you obtain:

 A=3.14(2.5 cm)^2 
 A=19.625 cm2

 The answer is: 19.625 cm^2

The equation is 1/2+3/x=3/4, it is still solvable
the equivalent of the equation is (1.x+2.3)/2.x = 3/4, or (x+ 6)/2.x=3/4, this last can be solved as follow: 4.(x+ 6) = 2x.3, 4x+ 24 = 6x, so 24=6x-4x=2x, and when 2x= 24 , it means x=24/2 =12, finally the equation is solvable because x=12 is a solution
