Answer:
A. .12
B. 2.1
C. 2.3
Step-by-step explanation:
Ok so first we have to find the square root of 9 which is 3 then divide 3 by 25 which is .12.
Next one. So the square root of 12 is about 3.5 And the square root of 3 is about 1.7. So 3.5 divided by 1.7 is about 2.1.
Last one. so the square root of 15 is about 3.9 and the square root of 3 is about 1.7. So 3.9 divided by 1.7 is about 2.3.

Option (2). 14 m
Step-by-step explanation:
Formula to get the area of a circle 'A' =
where r = radius of the circle
Given in the question,
Area of the circle = 153.86 square meters
By putting the values in the formula,
153.86 = πr²
r =
r =
r = 7 meters
Diameter of circle = 2 × (radius of the circle)
= 2 × 7
= 14 meters
Therefore, diameter of the circle is 14 meters.
Option (2) is the answer.
