Volume = area of base x height

area of base = 1/2 x base x height x number of central angles

area of base = 1/2 x 7 x 6.1 x 6 = 128.1

volume = 128.1 x 19 = 2433.9 cubic feet

Anna [14]

Step-by-step explanation:

The given expression is :

$\dfrac{2-\sqrt5}{2+3\sqrt5}=\sqrt5 x+y$ ....(1)

Taking LHS of the above expression

$\dfrac{2-\sqrt5}{2+3\sqrt5}$

Rationalizing both denominator and numerator.

$\dfrac{2-\sqrt5}{2+3\sqrt5}\times \dfrac{2-3\sqrt5}{2-3\sqrt5}=\dfrac{4-6\sqrt5-2\sqrt5+15}{2^2-(3\sqrt5)^2}\\\\=\dfrac{19-8\sqrt5}{4-45}\\\\=\dfrac{19-8\sqrt5}{-41}\\\\=\dfrac{\sqrt5 \times 8}{41}+(\dfrac{-19}{41})$
