1. The lenght BC is the hypotenuse of the triangle and to find its value, we must apply:

Sin(α)=opposite leg/hypotenuse

The opposite leg is14 ft.
The hypotenuse is BC.
The Angle "α" is 45°.

2. Let's substitute in the formula:

Sin(α)=opposite leg/hypotenuse
Sin(45°)=14/BC

3. When we clear BC, we obtain:

BCxSin(45°)=14
BC=14/Sin(45°)

4. Then, the result is:

BC= 14√2 ft

5. What is the length of BC?

The answer is: The length of BC is 14√2 ft

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

Can I get some help please 11 and 12

Xelga [282]

#11 is 2 ounces because there are 16 ounces in 1 pound and if u add all the #rs you get 32, divide by 16 and u get 2.
#12 is 10 ounces because when u add the #rs up u get 54. u subtract that from 64 because that's how many ounces are in 4 pounds, so ur answer is 10
