Answer:
Arc length of circle with circumference 18 and an arc with a 120° central angle is:
6
Step-by-step explanation:
The arc length of a circle is given by:
Here, circumference=18
i.e. 2πr=18
and
Arc length=
Hence, Arc length of circle with circumference 18 and an arc with a 120° central angle is:6

Answer:
94.954 ft³
Step-by-step explanation:
The formula for the volume of a cone is V = (1/3)(base area)(height).
Here the circumference of the base is C = 2πr = 22.608 ft = 2(3.14)r, which enables us to find r:
r = (22.608 ft) / (6.28) = 3.6 ft
The formula for the volume of a cone is V = (1/3)(base area)(height).
Using the given data, we have The formula for the volume of a cone is V = (1/3)(πr²)(7 ft), or
V = (1/3)(3.14)(3.6²)(7 ft), or
= 94.954 ft³
First distribute the negative
(-x+2)(x-7)
Next multiply -x by x
Then multiply 2 by x
Then multiply -x by -7
Then multiply 2 by -7
-x^2+2x+7x-14
-x^2+9x-14 is your answer
He will have to pay $3.25.
Let the number of miles traveled by a driver be x
The toll paid by the driver is then represented as $y.
Since there is a linear relation between the two, we can assume the equation can be written as:
y = mx + c
From the given data, we get
0.24 = m(0) + c
c = 0.25
Using the second point:
1 = m(1) + 0.25
m = 1 − 0.25 = 0.75
Hence, the equation is y = 0.75x + 0.25.
If x = 4, then:
y = 0.75 × 4 + 0.25
y = $5.50
Hence, He will have to pay $3.25.
