Answer:
a-b b-50%
Step-by-step explanation:
Let's see: 3+3+3=9
So
3*3=9
and so does
1*9=9
Series would be: 1,3,5......99
Here, a=1, d = 3-1 = 2, l = 99
l = a+(n-1)d
99 = 1+(n-1)2
98 = 2n-2
2n = 100
n = 50
Sum would be Sn = n/2 (a+l)
50/2 (1+99)
25(100) = 2500
So, your answer is 2500
Answer:
Step-by-step explanation:
Earth volume is approximately V = (4/3)πr³, and
Uranus volume is approximately V = (4/3)π(4r)³, or (4/3)π*64*r³
Comparing these two results, we see that the volume of Uranus is approximately 64 times greater than the volyume of Earth.
