Option B
48th term of arithmetic sequence is -152
<h3><u>
Solution:</u></h3>
Given that a arithmetic sequence has explict formula,
![a_n = -11 + (n - 1)(-3)](https://tex.z-dn.net/?f=a_n%20%3D%20-11%20%2B%20%28n%20-%201%29%28-3%29)
To find: 48th term of the arithmetic sequence
The nth term of arithmetic sequence can be found by substituting the required value of n in the explict formula
So 48th term of the arithmetic sequence can be found by substituting n = 48 in explict formula
![a_n = -11 + (n - 1)(-3)](https://tex.z-dn.net/?f=a_n%20%3D%20-11%20%2B%20%28n%20-%201%29%28-3%29)
Plug in n = 48
![a_{48} = -11 + (48 - 1)(-3)](https://tex.z-dn.net/?f=a_%7B48%7D%20%3D%20-11%20%2B%20%2848%20-%201%29%28-3%29)
On solving we get,
![a_{48} = -11 + (47)(-3)\\\\a_{48} = -11 - 141\\\\a_{48} = - 152](https://tex.z-dn.net/?f=a_%7B48%7D%20%3D%20-11%20%2B%20%2847%29%28-3%29%5C%5C%5C%5Ca_%7B48%7D%20%3D%20-11%20-%20141%5C%5C%5C%5Ca_%7B48%7D%20%3D%20-%20152)
Thus 48th term of arithmetic sequence is -152
The solid in the picture is a cylinder; thus, we can use the following formula:
![V=\pi*r^2h](https://tex.z-dn.net/?f=V%3D%5Cpi%2Ar%5E2h)
This formula works even if the solid is slanted.
The radius is 6 cm and the height is 5 cm.
![r=6](https://tex.z-dn.net/?f=r%3D6)
![h=5](https://tex.z-dn.net/?f=h%3D5)
Plug in these values into the volume formula.
![V=\pi*r^2h](https://tex.z-dn.net/?f=V%3D%5Cpi%2Ar%5E2h)
![=\pi*6^2*5=\pi*36*5=180 \pi](https://tex.z-dn.net/?f=%3D%5Cpi%2A6%5E2%2A5%3D%5Cpi%2A36%2A5%3D180%20%5Cpi)
The volume is 180π cm³. I hope this helps! :)
