I think it is 4/4 then, 4/6 then, 4/8. That is from greatest to least. I hope I helped ! :-)
Answer:
The answer is 1:2
Step-by-step explanation:
For small circle
r = 4
2πr = 2 × 3.14 × 4 = 25.12
For big circle
r = 8
2πr = 2 × 3.14 × 8 = 50.24
Now,
if we divide both answers we get,
25.12 ÷ 50.24 = 1/2 = 1:2
Answer:
8
Step-by-step explanation:
4 × 16= 64
√64 = 8
hope this helps...
1/6 and 1/2.
Multiply them together you get 1/12.
Answer:
The first term of the geometric series is 1
Step-by-step explanation:
In this question, we are tasked with calculating the first term of a geometric series, given the common ratio, and the sum of the first 8 terms.
Mathematically, the sum of terms in a geometric series can be calculated as;
S = a(r^n-1)/( r-1)
where a is the first term that we are looking for
r is the common ratio which is 3 according to the question
n is the number of terms which is 8
S is the sum of the number of terms which is 3280 according to the question
Plugging these values, we have
3280 = a(3^8 -1)/(3-1)
3280 = a( 6561-1)/2
3280 = a(6560)/2
3280 = 3280a
a = 3280/3280
a = 1
