Anni [7]
To solve this problem you must apply the proccedure shown below:

 1. You have the following information given in the problem above: The<span> regular octahedron with edges that are 2.1 inches.

 2. Therefore, you must apply the formula for calculate the volume of a octahedron, which is:

 V=(a^3</span>√2)/3

 3. Therefore, you have:

 V=((2.1 inches)^3√2)/3
 V=178.30 inches^3

The capacity of a cylindrical water tank is 539 litres. If its height is 1.4 meter then find the radius of the base.​
natulia [17]

Answer:

350m

Step-by-step explanation:

  • capacity= volume/1000
  • but we know that volume of cylinder is πr²h so substitute it I'm the volume space
  • then substitute for π as 22/7, h as 1.4 , and also capacity as 539
  • 539= ((22/7)×r²×1.4)/1000
  • when you simplify you get r as 350m

Write a system of linear equations with -3,9 as its solution
lozanna [386]
Let the variable of the equation be x.

Solution of the equation is given to us, hence,

x = -3               and           x = 9

x + 3 = 0          and           x - 9 = 0

Multiplying,

(x + 3)(x - 9) = x² - 9x + 3x - 27 = x² - 6x - 27

Hence, the linear equation with solution -3 and 9 is x² - 6x - 27.
