Answer:
[tex]C = 45 * 2\pi[/tex]
[tex]C = 90\pi[/tex]
Step-by-step explanation:
Given
[tex]h = 90[/tex] -- height of the wheel
Required
The expression for the distance traveled in 1 revolution
The height of the wheel implies that:
[tex]d =90[/tex] --- diameter equals height
The distance in 1 revolution is calculated by calculating the circumference of the wheel using:
[tex]C = 2\pi r[/tex] or [tex]C = \pi d[/tex]
Where
[tex]r = \frac{1}{2} * d[/tex]
[tex]r = \frac{1}{2} * 90[/tex]
[tex]r = 45[/tex]
So, we have:
[tex]C = 2\pi r[/tex]
[tex]C = 2\pi * 45[/tex]
[tex]C = 45 * 2\pi[/tex]
[tex]C = \pi d[/tex]
[tex]C = \pi * 90[/tex]
[tex]C = 90\pi[/tex]

Answer:
38
Step-by-step explanation:
Complement means that the 2 angles add up to 90 so:
x + 52 = 90
x = 90 - 52
x = 38

I assume you are looking for the points at which the parabola and line cross. In that case, this is rather simple. You can look at it and see where on the graph the points are.
5) In the figure, triangle ABC is a right triangle at B. If CD = 15, find BC to the nearest tenth.
Answer:
BC ≈ 4.0
Step-by-step explanation:
∠ DCA = 180° - 70° = 110° ( adjacent angles )
∠ DAC = 180° - (30 + 110)° ← sum of angles in triangle
∠ DAC = 180° - 140° = 40°
Using the Sine rule in Δ ACD to find common side AC
[tex]\frac{AC}{sin30}[/tex] = [tex]\frac{15}{sin40}[/tex] ( cross- multiply )
AC × sin40° = 15 × sin30° ( divide both sides by sin40° )
AC = [tex]\frac{15sin30}{sin40}[/tex] ≈ 11.668
Using the cosine ratio in right triangle ABC
cos70° = [tex]\frac{adjacent}{hypotenuse}[/tex] = [tex]\frac{BC}{AC}[/tex] = [tex]\frac{BC}{11.668}[/tex] ( multiply both sides by 11.668 )
11.668 × cos70° = BC , then
BC ≈ 4.0 ( to the nearest tenth )

What is the surface area of a cone with a 6 in. diameter and a length (slant height) of 8 in?
A. 11in^2
B. 75in^2
C. 104in^2
D. 179in^2
Answer:
The formula of a surface area of a cone:
SA=pi rl+\pi r^2SA=pirl+πr
2
r - radius
l - slant height
We have the diameter d = 6 in and a slant height l = 8 in.
d=2r\to r=6in:2=3ind=2r→r=6in:2=3in
Substitute:
SA=\pi(3)(8)+\pi(3^2)=24\pi+9\pi=\boxed{33\pi\ in^2}SA=π(3)(8)+π(3

Find the value of m if 13+24m=41m
Answer:
Step-by-step explanation:
13+24m=41m
13=41m-24m
13=17m
13/17=m
Answer:
Hey mate....
Step-by-step explanation:
This is ur answer.....
13 + 24m = 41m
13 = 41m - 24m
13 = 17m
= 13/17 = m

What is the area of the hexagon? 5 cm 8 cm 9.28 cm
Answer:
57.12 cm²
Step-by-step explanation:
The given dimensions of the hexagon are;
The side length of the hexagon, s = 5 cm
The distance across flats = 8 cm
The distance across corners = 9.28 cm
The area of a regular hexagon, 'A', is given as follows;
[tex]A = \dfrac{3 \cdot \sqrt{3} }{2} \cdot s^2= \dfrac{1}{2} \cdot P \cdot a = 3\cdot s\cdot h[/tex]
Where;
a = The side length of the hexagon
P = The perimeter of the hexagon
h = The height of one of the triangles in the hexagon
However with the given dimensions, the area of the hexagon can be found by finding the sum of the areas of the triangles that make up the rectangle
A₁ = A₃ = A₄ = A₆ = (1/2) × 4.64 cm × 4 cm = 9.28 cm²
A₂ = A₅ = (1/2) × 5 cm × 4 cm = 10 cm₂
The area of the hexagon, A = A₁ + A₃+ A₄ + A₆ + A₂ + A₅ = 4 × A₁ + 2 × A₂
∴ A = 4 × 9.28 cm² + 2 × 10 cm² = 57.12 cm²
2 × (5×4/2 + 2×9.28/4×4) = 57.12 cm²
The area of the hexagon, A = 57.12 cm²

B
Answer:
Area of segment = 9.8 cm² (Approx.)
Step-by-step explanation:
Given:
Angle θ = 120°
Radius of circle = 4 cm
Find:
Area of segment
Computation:
Area of segment = [θ/360][π][r]² - [1/2][r²][sinθ]
Area of segment = [120/360][3.14][4]² - [1/2][4²][sin120]
Area of segment = [0.333][3.14][16] - [0.5][16][0.866]
Area of segment = 16.7299 - 6.28
Area of segment = 9.8019
Area of segment = 9.8 cm² (Approx.)

If A and B are supplementary angles and A is times as large as B, find the measures of A and B.
Given circle Q with a measure of SR=120° and a radius of 9 feet, as shown below.
Determine the arc length of SR. Use mathematics to explain how you determined your answer❤️
Answer:
The arc length of the entire circle would be 2*PI*9
We need to know the arc length of 1/3 of the circle so we calculate
arc length = (2 * PI * 9) / 3
arc length = 2 * PI * 3
arc length = 6 * PI
arc length = 18.8495559215

On a map of North Carolina, the distance between Raleigh and Charlotte is 1 point
3 inches. The scale on the map is 1 inch = 40 miles. What is the actual
distance?
Answer:
52 miles
Step-by-step explanation:
You can use simple law of proportions to calculate this one.
[tex]\frac{1.3 inch}x} = \frac{1inch}{40mile}\\x= 52 miles[/tex]
solve for x and you get 52 miles.

Find the length of arc AB with an angle measure of 15 degrees and radius of 10 cm. Round to the nearest hundredth place if you get a continuous decimal when dividing with 360 degrees.
Answer:
AB ≈ 2.62 cm
Step-by-step explanation:
The arc AB is calculated as
AB = circumference of circle × fraction of circle
= 2πr × [tex]\frac{15}{360}[/tex]
= 2π × 10 × [tex]\frac{1}{24}[/tex]
= [tex]\frac{20\pi }{24}[/tex]
