V = d / t => t = d / V
V ≥ r ; d = 350 => t = d / V ≤ 350 / r
Then, t ≤ 350 / r, which is option C.
Answer:
67.17
Step-by-step explanation:
First, identify the hundreds digit (the 7)
Next, identify the next smallest place value (the 1)
Then, determine if 7 greater than or equal to 1. Yes, it is greater than 1, so round up. Increase the hundreds digit by one, so 7 becomes 8.
Finally, keep .17 and you get an answer of 67.17.
The number of seconds in a year are 31,557,600 seconds, which gives;
There are approximately Pi times 10,000,000 seconds in one <u>year</u>.

<h3>How can the given statement be completed?</h3>
The number of seconds in one day = 86,400
The number of seconds in one week = 604,800
The number of seconds in a year = 31,557,600
Therefore;

Which gives;
The number of seconds in a year ≈ π × 10,000,000
The completed statement is therefore;
- There are approximately Pi times 10,000,000 seconds in one <u>year</u>

Answer:
<h2>A) 3 cm</h2>
Step-by-step explanation:
The formula of a volume of a cylinder:

r - radius
H - height
We have r = 1cm and H = 21cm. Substitute:

The formula of a cone:

r - radius
H - height
We have V = 21π cm³ and H = 7cm. Substitute:
<em>divide both sides by π</em>
<em>divide both sides by 7</em>
<em>multiply both sides by 3</em>
