Answer:
62.83 
Step-by-step explanation:
The equation is V(Volume) equals π (Pi/3.14) multiplied by r(radius) squared multiplied by h(height). The way it would be written out is V=π×
×h. So when you plug in the radius (2) and the height (5) you get π×
×5 which equals 62.83185 or 62.83. I hope this helps you understand and if you need more help let me know.
No, there is not common ratio...
0.972 (common ratio is 0.3...10.8*.3*.3)
you can use the geometric mean to find this center value easily...
(18*8)^(1/2)=12
9x+8y=15
9x+8y=30
There can't be a solution because 9x+8y equal different things in both.
Hope this helps :)
Answer:
Step-by-step explanation:
nth term = a +(n-1)d
a3 = 116 ; a + 2d = 116 ---------(i)
a7 = 180; a + 6d = 180 -------(ii)
multiply (ii) by -1. so a will be eliminated
a + 2d = 116 ---------(i)
(ii)*-1 <u>-a - 6d = -180</u> -------(ii) { Now add the two equations}
- 4d = -64
d = -64/-4
d = 16
Plug in the value of d in equation (i),
a + 2*16 = 116
a + 32 = 116
a = 116 - 32
a = 84
12th term = 84 + 11* 16 = 84 + 176 = 260
A+b=(-3n+2)+(5n-7)
=(5-3n)+(2-7)
=2n-5
Came up with the same answer as the first guy
