A line horizontally drawn from the center of the circle is Radius, the correct option is A.
We are given that;
The statement a line horizontally drawn from the center of the circle
Now,
The tangent theorem of a circle states that a line is said to be tangent if it's perpendicular to the circle drawn to the point of tangency.
A radius is a line segment that joins the center of a circle to any point on its circumference.
A circle has infinitely many radii, and they are all equal in length.
Therefore, by circle the answer will be radius.

The answer is the radius
Answer:
7th turns
Step-by-step explanation:
An angle that turn through n one-degrees is said to have an angle measure of n degree. An angle that turns through 1/360 of a circle is called a one degree angle, this is used to measure angles
:. measure of the angle turns through 50 one degree angles
= = 7th turns.
The formula to get the circumference is 2πr, π being pi and r being your radius.
Your r is 0.9 since the radius is half the diameter.
2πr = 2 x 3.142 x 0.9
= 5.6556cm
≈ 5.7cm
