In order to increase the circumference of a circle from 12π cm to 18π cm, by how much must the diameter increase?
Vadim26 [7]

Answer:


Step-by-step explanation:

It's actually 6 cm. This is because the diameter of the smaller circle is 12pi/pi which is 12, and the diameter of the bigger one is 18pi/pi which is 18. 12 + 6 = 18, so the diameter increases by 6.

Anni [7]

Answer:

23 or more chairs.

Step-by-step explanation:

There are 5 tables to start. Each tables is 450 dollars.

5x450=2250

4500-2250=2250

2250(money still need to be made) divided by 100(the price of a chair)=22.5

Since you can't have a half of a chair but you cant have any less, you round it up to 23 chairs. The answer is 23 or more chairs.
