The ratio of the lengths EF and AD will be 2:1
<h3>How to get the ratio?</h3>
Given is a circle A with points B, C, D, E, F, and I on its circumference. A line joining any two points on the circumference of any circle is called a chord of the circle. Here BC, EF, and HI are chords of the circle.
A line joining center A and any point on the circumference of the circle is called the radius of the circle. Here AD is the radius of the circle.
Any chord that is passing through the center of the circle is called the diameter of the circle. Here EF and HI are diameters of the circle.
A diameter is always twice the length of the radius. So the ratio of diameter to radius will be 2:1.
Hence, the ratio of the lengths EF and AD will be 2:1

Answer:
0.23
Step-by-step explanation:
A formula I like to use to find the answer to these types of questions is
first, multiply 828×100=82,800
now divide 82800÷3600=23
so your answer is 23%==0.23
