The inequality that is true is 7π > 21
<h3>How to determine the inequality that is true?</h3>
To do this, we simply test the given inequalities (starting from the first)
The first inequality is represented as
7π > 21
Divide both sides of the inequality by 7
So, we have:
7π/7 > 21/7
Evaluate the quotient of 21 and 7
So, we have:
7π/7 > 3
Evaluate the quotient of 7π and 7
So, we have:
π > 3
The above inequality is true.
This is so because π = 3.14 and 3.14 > 3
Hence, the inequality that is true is 7π > 21

Looks good to me. Calculation is correct. Although you might want to add to #1 your description; that the width of the rectangle is the circumference of the circle (w = 2πr) and that you add the surfaces together to get the total surface area.
total surface area = area of rectangular part + area of circular parts
SA = 2πrL + 2πr²
Answer:
This question seems to be incomplete, I guess that we have a circular pool, with a diameter of 3.5 m.
Now, the circunference of a circle can be written as:
C = 2*pi*r
where:
pi = 3.14
r = radius = half of the diameter = 3.5m/2 = 1.75m
Then replacing those values in the equation for the circumference we have:
C = 2*3.14*1.75m = 10.99 m.
And knowing that the value of pi is actually larger than 3.14 (pi = 3.1415926535....)
We can safely round up the circumference to the next whole number, C = 11m
Answer:
is rational number.......
Step-by-step explanation:
Hey, there!!
Let's simply work with it,
60° + 2x° + (2x+12)° = 180° { being a linear pair}.
or, 72° + 4x = 180°
4x = 180° - 70°

Therefore, the value of x is 27°.
Now,
2x° = (2×27)°= 54°
(2x+12)° = 2×27°+12°= 66°.
(x+2)= 27+ 2= 29°
Now, The left angle is 27°.
Therefore, The answer is option A.
