Find the angles of the rhombus if the ratio of the angles formed by diagonals and the sides of the rhombus is 6:5.
Ainat [17]

Answer: Angles are (\frac{1080}{11}) ^{\circ} and (\frac{900}{11})^{\circ}

Step-by-step explanation:

Here, the ratio of the angles formed by diagonals and the sides of the rhombus is 6:5.

Let the  angles formed by diagonals and the sides of the rhombus are 6x and 5x.

Where x is any number.

Thus, By the property of rhombus,

Diagonals perpendicularly bisect each other.

Therefore, 6 x + 5 x + 90^{\circ} = 180^{\circ}

⇒ 11 x + 90^{\circ} = 180^{\circ}

⇒ 11 x = 90^{\circ}

⇒ x = \frac{90}{11}

Therefore, the  angles formed by diagonals and the sides of the rhombus are (\frac{540}{11} )^{\circ} and (\frac{450}{11})^{\circ}

⇒ The angles of rhombus are  (\frac{1080}{11} )^{\circ} and  (\frac{900}{11})^{\circ}

Find the Volume (look at the picture)
xeze [42]

Answer:

V ≈ 263.9 units³

Step-by-step explanation:

The volume (V) of a cone is calculated as

V = \frac{1}{3} πr²h ( r is the radius and h the height )

Here r = 6 and h = 7 , then

V = \frac{1}{3} π × 6² × 7

   = \frac{1}{3}π × 36 × 7

   = \frac{1}{3}π × 252

   = 84 π

   ≈ 263.9 units³ ( to 1 dec. place )
