Area of a cylinder is the area of the top + the area of the bottom + the area of the wrap-around (lateral)
top: pi*r*r=81pi
bottom: 81pi
lateral: 2pi*r*h=18pi*h, h is unknown, but you don't have to solve it.
add them up: 81pi +81pi + 18h*pi=1850
pi*h=(1850-162pi)/18, (plug this in the volume formula below.)
volume of a cylinder: the area of the base × the height =81pi*h
volume=81[1850-162pi)/18]
use your calculator: V=6036
please double check my calculation by yourself.

aₙ=aₙ-₁ +19
Answer:
The answer is (-1/2)
Step-by-step explanation:
<h3><u>Given</u>;</h3>
<h3><u>To </u><u>Find</u>;</h3>
So,
24d = -12
Divide both side by 24 we get,
24d/24 = -12/24
d = -1/2
Thus, The value of d is (-1/2)
