what is the surface area of a conical grain storage tank that has a height of 24 meters and a diameter of 16 meters? round the answer to the nearest square tenth.

Answers

The basis of this cone is a circle with a diameter d = 16m. This information is sufficient to calculate
1. The surface of the wheel . We use the formula

A = \pi r^(2) 

2. 
the radius of the wheel needed to the formula for calculating the area of ​​a circle and the cone

d = 16m
1/2d = r = 1/2*16m = 8m
..................................................................................................
Area base
P = \pi r^(2) = \pi (8m)^(2) = 64 \pi m^(2) 
..................................................................................................
The surface area

A = \pi rl 
l - creates a cone = ?

Height , forming a cone and the radius of a circle formed triangle . Two known sides is possible to calculate the third side ( the cone ) of the Pythagorean Theorem

a = r = 8cm
b = h = 24m
c = l = ?

a² + b² = c²
r² + h²  = l²
l = √ (r² + h²) = √ [ ( 8m)² + ( 24m)² ] = √ (64m² + 576m²) = √ (640 m²)= √ (8*8*10m²) = 8√10m

The lateral surface of the cone
A = 
πrl = π*8m *8√10m = 64√10πm²

The total area of ​​the cone = The base area of ​​the side surface of +

A = 64
√10πm² + 64πm² = 64πm² *(√10 + 1)


What is the midpoint of the x-intercepts of f(x) = (x – 2)(x – 4)? A)(–3,0)
B)(–1,0)
C)(1,0)
D)(3,0)

Answers

Answer:

The correct option is D.

Step-by-step explanation:

The given function is

f(x)=(x-2)(x-4)

From the given graph it is clear that x-intercepts of the graph are (2,0) and (4,0).

The midpoint of x-intercepts is

Midpoint=((x_1+x_2)/(2),(y_1+y_2)/(2))

Midpoint=((2+4)/(2),(0+0)/(2))

Midpoint=((6)/(2),(0)/(2))

Midpoint=(3,0)

The midpoint of x-intercepts is (3,0). Therefore the correct option is D.

The x-intercepts are readily identified on the graph:  (2,0) and (4,0).  The midpoint of a line connecting those 2 points would be (3,0).

What is the Pythagorean theorem?

Pythagorean theorem states that in the right angle triangle the hypotenuse square is equal to the square of the sum of the other two sides. According to this statement, the areas of the squares on the other two sides add up to the size of the square whose side is the hypotenuse.

The value of c is calculated as:-

a² + b² = c²

It is given the rope is attached to the top of her tent and the rope the camper takes is 6ft long and tied to the ground. A right-angle triangle is formed with hypotenuse as 6 ft and height that one of the legs of the right triangle as 4 ft.

The length of the rope from the ground to the tent will be calculated as below:-

By Pythagoras's Theorem :

a² + b² = c²

4² + b² = 6²

b² = 36 - 16 = 20

b = √20 = 4.47 ft.

Therefore, the rope is tied 4.5 ft from the center of the tent.

Answer:The rope is tied 4.5 ft from the center of the tent.

Step-by-step explanation:

It is given the rope is attached from top of her tent and the rope the camper takes is 6ft long tied to the ground.A right angle triangle is formed with hypotenuse as 6 ft and height  that is one of the legs of the right triangle as 4 ft . We need to find the other leg of the right triangle which will represent the ground distance from the middle of tent to the point where the rope is tied .

By Pythagoras's Theorem :

a^(2) +b^(2) =c^(2)

Where a and b are the legs and c the hypotenuse of the right triangle.

Substituting the values of a and c we have:

4^(2) +b^(2) =6^(2)

or 16+b^(2) =36

b^(2) =36-16=20.

Tabing root of both sides b=4.47.

The rope is tied 4.5 ft from the center of the tent.
