and that h = 9

volume of cone = \frac{1}{3}*π*4^{2}*9

Answer:

214

Step-by-step explanation:

A circle is 360 degrees

Arc EF is 146 degrees

EF + EDF = full circle

146 + EDF = 360

Subtract 146 from each side

146-146 +EDF = 360-146

EDF =214

Why does sin54°≈0.809≈cos36° in a right triangle?
allsm [11]

9514 1404 393

Answer:

A

54° and 36° are complementary angles in the same right triangle. sin54° is the ratio of the opposite leg and the hypotenuse and cos36° is the ratio of the adjacent leg and the hypotenuse. In this triangle, the opposite leg of 54° and the adjacent leg of 36° are the same leg in the triangle.

Step-by-step explanation:

The answer explains itself.

The sum of angles in a triangle is 180°. When one of the angles is 90°, the sum of the other two angles is also 90°. That means those two acute angles are <em>complementary</em> (not supplementary).

The mnemonic SOH CAH TOA reminds you that ...

  Sin = Opposite/Hypotenuse

  Cos = Adjacent/Hypotenuse
