3n - 3n >= 8 - 15 arrange the like terms.
0 >= -7 combine the like terms.
Answer:
Step-by-step explanation:
What is the equation?
You need to replace all A with 3 and all c with 12. If I had the equation, I'd be glad to help further.
In geometry there are numerous formulas for specific shapes. However, you must know the basic concept to it so that you don't need to memorize a lot. For any given solid shape with equal bases, its volume is equal to the area of its base times its perpendicular height. But for pointed solids like a cone or a pyramid, the general formula of the volume is one-third of the product of the base area and the perpendicular height. For a cone, its base is circle, so:
V = `1/3 * πr² * h
The half of a diameter is the radius. So, r = d/2. Substituting the values
V = 1/3 * (3.14)(5/2)² * 7
V = 45.79 or 46 cm³
The answer is letter B.
