  • Sine of an angle = Opposite side/Hypotenuse

  • Cosine of an angle = Adjacent side/Hypotenuse

  • Tangent of an angle = Opposite side/Adjacent side

These three operators can be thought of as ratios of certain sides of a triangle. A ratio is just a comparison of two quantities; or lengths of the sides in this case.

Please consider the graph of the sphere.

We know that the volume of sphere is equal to \frac{4}{3}\pi r^3, where r represents radius of sphere.

We can see that diameter of sphere is 30 inches. We know that radius is half the diameter, so radius of the given sphere would be half of 30 inches that is \frac{30}{2}=15 inches.

V=\frac{4}{3}\pi r^3

V=\frac{4}{3}\pi (15\text{ in})^3

V=\frac{4}{3}\pi \times 3375\text{ in}^3

V=4\times 1125\pi \text{ in}^3

V=4500\pi \text{ in}^3

Therefore, the volume of the given sphere is 4500\pi\text{ in}^3 and option B is the correct choice.

The label on a juice carton says there are 50 calories in a 4-ounce serving of juice.
Scrat [10]
The answer is D
Because, if there is 50 calories in 4 ounce serving of juice, then you do how many times 4 equals 12. 3 times 4 equals 12. so you will use 3 to multiply by 50 and you get 150  calories in 12 ounces.
