Make a the subject of the formula x²=a²-a²w²​
Gwar [14]

Answer:

a = ± \sqrt{\frac{x^2}{1-w} }

Step-by-step explanation:

Given

x² = a² - a²w ← factor out a² from each term on the right side

x² = a²(1 - w) ← divide both sides by (1 - w)

\frac{x^2}{1-w} = a² ( take the square root of both sides )

± \sqrt{\frac{x^2}{1-w} } = a

So, of a player having less than 220 lb weight is 100%.and and we know that when we add or subtract from mean we get real values

Answer:

The volume of the solid = 96π inches³

Step-by-step explanation:

* The solid in the figure is a cone

* Lets revise the rule of the volume of the cone

- The volume of the cone formula is:

 V = (1/3) × area of the base × its height

∵ The base of the cone is shaped circle

∵ Area of the circle = π r²

∵ The length of the radius = 6 inches

∴ The area of the base = π (6)² = 36π inches²

* Now we can find the volume of the cone

∵ The length of the height of the cone = 8 inches

∴ V = (1/3) × 36π × 8 = 96π inches³

* The volume of the solid = 96π inches³
