Answer:
15
Step-by-step explanation:
1.5*10 =15
So we’re looking how many combinations we can make by selecting 5 items in a group of 17.
So we use n C r.
Where I the number of combinations of n objects taken r at a time.
So, 17 C 5
17! / (17-5)! 5! = 6188
(I hope this is correct)
Answer:
803.84 millimeters²
Step-by-step explanation:
How do we find the area of a circle?
- The area of a circle is πr², where r = radius. In this case, we have to approximate pi to 3.14.

Answer:
it's quite difficult
Step-by-step explanation:
I think it will...
500=4πr^2. first divide 500 from four which will equal 125, then divide 125 with π and it will equal 39.788 . finally √39.788. the answer will be r=6.3 or 6
