Given right triangle MNO, which represents the value of cos(M)?

laila [671]

Answer:

Option B. MN/MO

Step-by-step explanation:

In a right angle triangle cosine of any acute angle = Base/ Hypotenuse

In the ∠ NMO Hypotenuse is MO and base of the triangle is MN.

Therefore cos (M) = Base / Hypotenuse = MN / MO

Therefore option B is the right answer.

PLZZ HELP WILL GIVE BRAINIEST!An ice cream cone has a scoop of ice cream that is a half-sphere on top. What is the volume of the

Tpy6a [65]

Answer:

See example below.

Step-by-step explanation:

You'll need the height and radius of the cone to find the volume. Use the example below to find your solution.

Example:

The volume of the cone is found using the volume formula for a cone $V=\frac{1}{3}\pi r^2h$ .

Substitute h=18 and r = 6.

$V = \frac{1}{3}\pi r^2h\\V = \frac{1}{3}\pi (6^2)(18)\\V=\frac{1}{3}\pi *36*18\\V = \frac{648}{3}\pi \\V= 216\pi = 678.24$

A half sphere is a hemisphere. The volume of a hemisphere is half of $V=\frac{4}{3}\pi r^3$ . Substitute r=6.

$V=\frac{4}{3}\pi r^3\\V=\frac{4}{3}\pi 6^3\\V=\frac{4}{3}\pi *216\\V=\frac{4*216}{3}\pi\\ V=288\pi=452.6$

However the hemisphere is half this so it is $144\pi$ .

The total volume for this example is 452.6 + 678.24 = 1,130.84
