Change 2% to a decimal .02 times 7000000000 = 140,000,000
composite number means a number that can be formed by multiplying two smaller numbers
3n-1 for n=2, 3n-1=3*2-1=6-1=5
3n-1 for n=10, 3n-1=3*10-1=30-1=29
5 is composite because 2*2.5=5
29 is composite because 5*5.8=29
Answer:
17cm
Step-by-step explanation:
Given that the Volume of a cone is 4,000 cm³. And we need to determine the height of the cone , if the diameter is 30cm .
<u>Diagram</u><u> </u><u>:</u><u>-</u><u> </u>

Step 1: <u>Using</u><u> the</u><u> </u><u>formula </u><u>of</u><u> </u><u>cone </u><u>:</u><u>-</u><u> </u>
The volume of cone is ,
Step 2: <u>Substitute</u><u> </u><u>the </u><u>respective</u><u> </u><u>value </u><u>:</u><u>-</u><u> </u>
As Radius is half of diameter , therefore here r = 30cm/2 = 15cm .
Step 3:<u> </u><u>Simplify</u><u> the</u><u> </u><u>RHS </u><u>:</u><u>-</u><u> </u>
Step 4: <u>Move</u><u> </u><u>all </u><u>the </u><u>constant</u><u> </u><u>nos.</u><u> </u><u>to </u><u>one</u><u> side</u>

<u>Hence</u><u> the</u><u> </u><u>height</u><u> of</u><u> the</u><u> </u><u>cone </u><u>is</u><u> </u><u>1</u><u>7</u><u>c</u><u>m</u><u> </u><u>.</u>
1. √16 = 4
2. √2.25 = 1.5
3. 6^2 / 9 *2 = 8
4. 12-2 / 6+4 = 1
5. √16+9 = 5
6. 63 / 3^2 + |2| = 9
