Mathematics
1 answer:
Pavlova-9 [17]3 years ago

Answer:

The value of x is 9.

The value of y is 18.

Step-by-step explanation:

The given triangle is a right angled triangle.

We have: $ tan(x) = \frac{opp}{adj} $

Therefore, $ tan(30)  =  \frac{x}{9\sqrt{3}} $

Since, $ tan(30) = \frac{1}{\sqrt{3}} $

Therefore, we have:

$ \frac{1}{\sqrt{3}} = \frac{x}{9\sqrt{3}} $

$ \implies x = 9 $

Now, 'y' is the hypotenuse.

Use Pythagoras theorem, we have $ x^2 + (9\sqrt{3}})^2 = y^2 $

Substituting x = 9, we get:

81 + 81(3) = y²

$ \implies y^2 = 81 + 243 $

$ \implies y^2 = 324 $

$ \therefore y = 18 $

Hence, the value of y = 18.

Scrat [10]

Answer:

  • 1004.8 in³

Step-by-step explanation:

d = 2r => r = d/2 = 16in/2 = 8 inches

V = Ab×h

= π·r²×h

= 3.14·(8in)²×5in

= 1004.8 in³
