Answer:

Volume of the hive is 4712.4 square inches.

Step-by-step explanation:

Since hive has the shape of a cone with radius = 15 inches and height = 20 inches

Therefore, volume of the given cone = \frac{1}{3}(\text{Area of the base})\times \text{height}

Area of the circular base = πr²

Area = π(15)²

        = 225π

Volume of the cone = \frac{1}{3}(225\pi )\times{20}

                                 = 1500π

                                 = 4712.39

                                 ≈ 4712.4 square inches

Therefore, volume of the hive is 4712.4 square inches.

What is the measure of z? 3 27 y x z
Sholpan [36]

Answer: 3\sqrt{10}

Step-by-step explanation:

By the geometric mean theorem,

\frac{y}{3}=\frac{27}{y}\\y^{2}=81\\y=9

So, by the Pythagorean theorem,

3^{2}+9^{2}=z^{2}\\90=z^{2}\\z=\boxed{3\sqrt{10}}

A brace for a shelf has the shape of a right triangle. Its hypotense is 16 incges long and the two legs are equal in length. How
Len [333]
We use trigonometry because we know an angle and a side length. 

We are looking for one of the sides that isn't the hypotenuse:
As illustrated by the picture I made below:

We know both unknown angles will be 45 degrees, as there are 180 degrees in a triangle, we know the triangle is a right angle triangle (has 90 degrees) so, (180-90)/2 = 45

Using SOH CAH TOA, short for :  SIN- OH  COS- AH  TAN- OA

We are looking for the one with H, as we know what H is.
I am picking "SIN- OH", but we could use "COS- AH"

The formula for 
this is: Sin(angle) = O/H
<u />
<u>We substitute the angle (45) and the length for H (16)
</u>
Sin(45)= O/16 <- rearrange it
Sin(45)*16= O <- Solve in the calculator
13.6145 (4 DP)= O
The legs = O

The legs have a length of "13.6145 (4 DP)" each

6. A ship is on the surface of the water, and its radar detects a submarine at a distance of
Minchanka [31]

Answer:

the submarine is 92.994 feet ≈ 93 feet deep from the surface of the water

Step-by-step explanation:

We can think in a triangle where the hypotenuse is the detection distance and the angle with the horizontal surface of water is the depression angle, then the underwater distance is the vertical side of the triangle.

If we denote Ф  as the angle of depression ,d as the detection distance and x as the unknown depth of the submarine, using trigonometry:

x = d* sin Ф

thus

x=  d * sin Ф = 238 feet * sin 23° = 92.994 feet ≈ 93 feet
