<h2>
The volume of a cylinder (y) = 
</h2>
Step-by-step explanation:
Given by question,
The volume of a cylinder = y, The radius of a cylinder(r) = x - 3 and
The height of a cylinder(h) = 2x + 7
To find, the volume of a cylinder (y) = ?
We know that,
The volume of a cylinder = 
⇒ 
⇒ y =
⇒ y =
∴ The volume of a cylinder (y) =
Thus, the volume of a cylinder (y) =

Answer:
like -1/4
Step-by-step explanation:
( y - 4 ) ( y² + 4 y + 16 ) = y³ + 4 y² + 16 y - 4 y² - 16 y - 64
The result is a polynomial of the form:
y³ + 4 y² + a y - 4 y² - a y + 64;
Answer: a = 16
Answer:
The train ride is 3.5 hours
Step-by-step explanation:
We know that distance is equal to rate times time
d = rt
We know the distance and the rate
420 = 120*t
Divide each side by 120
420/120 = 120t/120
3.5 =t
The train ride is 3.5 hours
Answer:
1. 110 degrees.
2. 276 students.
Step-by-step explanation:
1. Converting the ratios to fractions:
3 + 4 + 11 = 18 so the largest angle is 11/18 of 180 degrees.
Answer is 180 * 11/ 18 = 110 degrees.
2. That would be 460 * 36 / 60
= 276 students.
