The diameter of <u>circle A</u> is 4.8. The correct option is the second option- 4.8
<h3>Calculating the diameter of a circle </h3>
From the question, we are to determine the diameter of circle A
From the given information,
Circle A is dilated by a <u>scale factor</u> of 2.5 to form circle B
That is,
If the diameter of circle A is d, then the diameter of circle B will be 2.5d
Also, from the given information,
Diameter of circle B = 12
Then, we can write that
2.5d = 12
∴ d = 12/2.5
d = 4.8
Hence, the diameter of <u>circle A</u> is 4.8. The correct option is the second option- 4.8

The diameter of the circle is 5.4 cm. The shaded area is 180 degrees, which is 1/2 of the circle.
Calculate the area of the full circle and divide by 2.
Area = PI x r^2
r = 5.4/2 = 2.7
Area = 3.14 x 2.7^2 = 22.90
Area of shaded part: 22.90 / 2 = 11.45 cm^2.
The answer is A.
Answer:
The length is APPROXIMATELY equal to 12.4.
Step-by-step explanation:
Use the converse of the Pythagorean Theorem (
+
=
[where "c" is both the longest side and the hypotenuse]) since a rectangle's diagonals will always cut it into two right triangles:
169-16=153.
