I'm not sure .... but I think you can use cross multiplication to find out the answer.... and then there's another step to finding the compatible numbera
I think that the basketball's volume would be greater than the softball because it has a radius of 5 and the softball has a radius of 2.
Answer:
d(n) = 85 * ( 3 - n )
Step-by-step explanation:
Let's find the common difference of the terms (if any).
The common difference is = 85 - 170 = 0 - 85 = -85 - 0 = -85
For an arithmatic sequence with first term a, common difference d,
nth term = a + ( n - 1 ) * d
So, d(n) = 170 + ( n - 1 ) * (-85)
= 255 - 85n
= 85 ( 3 - n )

C=2pir
first one is r=70
c=2pi70=140pi
2nd one is 49=r
c=2pir
c=2pi49
c=98pi
ratio is
140pi:98pi=10:7
