Given that the diameter of circle = twice the radius, the value of x = 4.7.
<h3>What is the Diameter of a Circle?</h3>
The diameter of a circle is a segment that divides the circle into two halves.
Diameter = 2(radius of circle).
Given:
Radius of circle = x + 1.5
Diameter = 9 2/5 = 9.4 cm
Therefore:
2(x + 1.5) = 9.4
2x + 3 = 9.4
2x = 9.4
x = 9.4/2
x = 4.7
Therefore, given that the diameter of circle = twice the radius, the value of x = 4.7.

Step-by-step explanation:
A/2 = 4
A = 4 x 2
A = 8
I think this should be the answer
Answer:
C.
Step-by-step explanation:
interior angles for ABCD is 360° and for ABO(triangle above) is 180°
from triangle,
you will get angle for OBA which is 180° - 38° - 90° = 52°
from angle B, we know that, straight line is 180°.
so,
180° = 52° +y- 12°
y = 140°
so, we can calculate x.
360° = 90° + 90° + 128° + x
x = 52°
Its the third one because the other ones do not make since becuase its something you are not going to do
