Ok so I created a equation to see how many seconds can you go to get to 180. The equation is 0.4x = 180 and I got 450. Now I concluded from this result the inequality is A, x < 450 because unless you want your submarine to crash in the seafloor you should probably stop before 450 seconds.
The nearest whole number the diameter of the circle is 5.0 cm.
<u>Given the following data:</u>
- Circumference of a circle = 15.4 cm
To estimate to the nearest whole number the diameter of the circle:
In this exercise, you're required to solve for the diameter of a circle and round up its value to the nearest whole number.
<h3>How to calculate the circumference of a circle.</h3>
Mathematically, the circumference of a circle is given by the formula:

<u>Where:</u>
- D is the diameter of a circle.
Making D the subject of formula, we have:

Substituting the given parameters into the formula, we have;

D = 4.90 cm
To the nearest whole number:
D = 4.90 ≈ 5.0 cm
