A grain silo has a diameter of 4.4 meters. The height of its cylindrical portion is 6.2 meters.
erastova [34]
Volume of a cylinder = Height x base are
H = 6.2 m
Bae are = π.R² ; Diameter =4.4 m, then Radius = 2.2 m
Base area = π(2.2)²
And Volume=:
V= (6.2).(π,2.2²) = (6.2).(π)(.4.84) = 30.008.π ≈ 94.2 m³

Solve the equation, and check the solutions √(x+9)/4=3.
nadya68 [22]

Answer:

Solution: x = 135

Step-by-step explanation:

Hi there!

First, let´s write the equation:

√(x + 9) /4 = 3

Multiply by 4 both sides of the equation

√(x + 9) = 12

square both sides of the equation

x + 9 = 144

subtract 9 to both sides of the equation

x = 135  

Let´s check the solution:

√(x + 9) /4 = 3

x = 135

√(135 + 9) /4 = 3

√(144) /4 = 3

12/4 = 3

3 = 3

Then, x = 135 is the solution to the equation.

Have a nice day!
