Mathematics
1 answer:
rosijanka [135]2 years ago
7 0

Answer:

-(√105)/11

Step-by-step explanation:

Tangent is the ratio of sine to cosine. When tangent is positive, sine and cosine have the same sign. This means the appropriate choice will be either the first one or the last one.

cos(θ) = -√(1 - sin(θ)²) . . . . in the 3rd quadrant

... = -√(1 - (-4/11)²)

... = -(1/11)√(121 -16)

... = -(√105)/11 . . . . . . matches the first selection

What is the approximate volume of one refraction cup? What’s its formula ?
Marizza181 [45]

Answer:

Volume = 0.1696 L

The formula is Area of base of refraction cup × Depth of the refraction cup

Step-by-step explanation:

The dimensions of a refraction cup are;

Diameter = 120 mm

Depth = 30 mm

Therefore, volume of the refraction cup = Area of base × Depth

Volume of the refraction cup = (π×120²/4)/2 × 30 = 169646.003 mm³

1 L = 1000000 mm³

Therefore, 169646.003 mm³ = 169646.003/1000000 m³ = 0.1696 L

The formula is Area of base of refraction cup × Depth of the refraction cup.
