Answer:
The area of the sector (shaded section) is 29.51 [tex]m^{2}[/tex].
Step-by-step explanation:
Area of a sector = (θ ÷ 360) [tex]\pi[/tex][tex]r^{2}[/tex]
where θ is the central angle of the sector, and r is the radius of the circle.
From the diagram give, diameter of the circle is 26 m. So that;
r = [tex]\frac{diameter}{2}[/tex]
= [tex]\frac{26}{2}[/tex] = 13 m
θ = 360 - (180 + 160)
= 360 - 340
= [tex]20^{o}[/tex]
Thus,
area of the given sector = [tex]\frac{20}{360}[/tex] x [tex]\frac{22}{7}[/tex] x [tex](13)^{2}[/tex]
= [tex]\frac{20}{360}[/tex] x x [tex]\frac{22}{7}[/tex] x 169
= 29.5079
The area of the sector (shaded section) is 29.51 [tex]m^{2}[/tex].

A number, x, rounded to 1 decimal place is 3.7
Write down the error interval for x.
Answers
Answer:
The error in rounding a number is half of the unit of measure. The number was rounded to the nearest 0.1 unit so the error is half of 0.1 which is 12⋅0.1=0.05

⋅0.1=0.05. Since 3.7+0.05=3.753.7+0.05=3.75 and 3.7−0.05=3.653.7−0.05=3.65, then the error interval is \boxed{3.65\le x<3.75}.

The area of a circle is 201 square meters. Find
the radius.
Answers
Answer:
8.0meters
Step-by-step explanation:
Given data
Area of cirlce= 201 square meters
The expression for the area is
A=πr^2
Substitute our area
201= 3.14*r^2
r^2= 201/3.14
r^2= 64.01
square both sides
r= √64.01
r= 8.0 meters
Hence the radius is 8.0meters

For this problem, the method I used was more of a guess and check because I simply plugged the options into a calculator to see which one would be closest a little bit past 9.3 but not all the way 9.4
the square root of 87 is 9.32 so you would round down while the square root of 88 is 9.38 which would round up

Topografía. La superficie de una montaña se modela mediante la ecuación ℎ(, ) = 5000 − 0.001 2 − 0.004 2 . Un montañista se encuentra en el punto (500, 300, 4390). ¿En qué dirección debe moverse para ascender con la mayor rapidez?
Answers
Respuesta:
(-1, - 2,4)
Explicación paso a paso:
Dada la función:
ℎ (x, y) = 5000 - 0,001x2 - 0,004y2
Tomando la derivada parcial con respecto a ambas direcciones (xey) se obtiene la dirección del vector de gradiente, donde es posible el movimiento más rápido
H '(x, y) = (dh / dx, dh / dy)
dh / dx = 2 (-0.001x) = - 0.002x
dh / dy = 2 (-0.004y) = - 0.008y
H '(500, 300) = (- 0,002 (500); - 0,008 (300))
H '(500, 300) = (- 1; - 2,4)
Por lo tanto, el montañista ascenderá con la mayor velocidad en el punto (-1, - 2.4)

The volume of a cylinder is 54π cubic inches and the height is 6 inches. Find the radius.
Answers
Answer:
The radius of the cylinder is 3 inches.
Step-by-step explanation:
For any given cylinder, the volume can be expressed as:
volume = [tex]\pi[/tex][tex]r^{2}[/tex]h
where r is the radius of its circular surface, and h is its height.
Given that: volume = 54π cubic inches, and the height = 6 inches.
then,
54[tex]\pi[/tex] = [tex]\pi[/tex] x [tex]r^{2}[/tex] x 6
54[tex]\pi[/tex] = 6[tex]\pi[/tex][tex]r^{2}[/tex]
[tex]r^{2}[/tex] = [tex]\frac{54\pi }{6\pi }[/tex]
= 9
r = [tex]\sqrt{9}[/tex]
r = 3
The radius of the cylinder is 3 inches.
