please explain it.
I will Mark Brain list. if explain
​

Answer 1

Step-by-step explanation:

Join point A and center using pythagoras theorem.

( hypotenuse) square = ( side 1) square + ( side 2) square

( AC) square = 576 + 49

( AC) square = 625

AC = 25

Radius = 25

Diameter = 2 × Radius

Diameter = 2 × 25

Diameter = 50
