The formulas for arc length and area of a sector are quite close in their appearance. The formula for arc length, however, is related to the circumference of a circle while the area of a sector is related to, well, the area! The arc length formula is
. Notice the "2*pi*r" which is the circumference formula. The area of a sector is
. Notice the "pi*r squared", which of course is the area of a circle. In our problem we are given the arc length and the radius. What we do not have that we need to then find the area of a sector of the circle is the measure of the central angle, beta. Filling in accordingly,
. Simplifying by multiplying by 360 on both sides and then dividing by 36 on both sides gives us that our angle has a measure of 60°. Now we can use that to find the area of a sector of that same circle. Again, filling accordingly,
, and
. When you multiply in the value of pi, you get that your area is 169.65 in squared.
<u>Answer-</u>
<em>The equation that could represent the distance traveled by Bus B is </em><em>y = 40x</em>
<u>Solution-</u>
On abscissa time in hour is represented and on ordinate distance in km is represented.
The equation for Bus A is given by,
Comparing it with the general slope-intercept equation of straight line,
Where,
m = slope = 55
c = y-intercept = 0
We know that slope is measured as the tangent of the angle made by the line with positive x-axis measured in counter-clockwise direction.
Slope for Bus A = m₂ = tan θ₂
Slope for Bus B = m₁ = tan θ₁
From the properties of trigonometric function,
From the given option, only the first option has a straight line equation with slope less than m₂ or 55, which is 40.
Therefore, the equation that could represent the distance traveled by Bus B is y = 40x
Answer:
um uhhhh err ima say a flat 500
Step-by-step explanation:
i added 200 to 100 and got bored so added another 200 :D
The final step. You divided wrong.
8 = 400 / 120 = 10/3
