![\rule[225]{225}{2}](https://tex.z-dn.net/?f=%5Crule%5B225%5D%7B225%7D%7B2%7D)
Step-by-step explanation:
Let the number be x.

Dividing both sides by 4,

Subtracting 8 from both sides,

The number is -7.

Answer:
C. π(2ft)²(10ft) + 1/3π(2ft)²(13ft-10ft)
Step-by-step explanation:
Given:
diameter = 4ft
length of the cylindrical part = 10ft
entire length of the silo = 13ft
Find the volume of the silo = volume of cylinder and volume of the cone
Formulas:
Volume of cylinder: πr²h
Volume of come: 1/3πr²h
2ft= radius
height =10
volume π×2²×10
radius 2ft
height 13-10=3ft
Volume= 1/3×π×2²×3 cube feet
Therefore the third answer is correct: C. π(2ft)²(10ft) + 1/3π(2ft)²(13ft-10ft)
