Acircle passes through opposite vertices of a square with side 40cm. if the diagonal of the square is a diameter of a circle, calculate the radius of the circle.

28.28cm

Step-by-step explanation: since the squares sides is 40 then draw lines diagonally in the circle and then they'll make triangles and find the hypotenuse then the 56.56 which is the diameter is divided by two to find the radius

let's solve your equation step-by-step.

4x+2=2x+12

step 1: subtract 2x from both sides.

4x+2−2x=2x+12−2x

2x+2=12

step 2: subtract 2 from both sides.

2x+2−2=12−2

2x=10

step 3: divide both sides by 2.

2x

2

=

10
