Speed of the train = 180km/hr
Now, distance from Grenoble to Paris = 480 km
Speed = Distance/Time
We know the speed and distance.So, from this we can find time :)
180 km/hr = 480 km /Time
Time = 480/180 = 2.66 hrs ≈ 2.7 hr
Therefore, the answer is D.2.7 hr
Answer:
This would be <em>length = 4</em> and <em>width = 4</em>
Step-by-step explanation:
This is because to find the area of a rectangle its length x width.
So the two numbers that multiply to 16 is 4 and 4.

<h3>Exact area = 12pi - 9*sqrt(3) square inches</h3><h3>Approximate area = 22.1106545749577 square inches</h3>
==========================================================
Work Shown:
Assuming the chord is horizontal along with the diameter, then this means the two smallest minor arcs are both 30 degrees each. This leaves the northern most arc to be 180-30-30 = 120 degrees in measure
A = area of northern sector (you can think of it as a pizza slize)
A = (angle/360)*pi*r^2
A = (120/360)*pi*6^2
A = 12pi
B = area of triangle
B = (1/2)*side1*side2*sin(included angle)
B = (1/2)*6*6*sin(120)
B = 18*sqrt(3)/2
B = 9*sqrt(3)
C = area of shaded region
C = A - B
C = 12pi - 9*sqrt(3) .... exact area
C = 22.1106545749577 ... use a calculator to get the approximate area
Answer:
Step-by-step explanation:
you can round the numbers
27/3= 9
27.36 rounds down to 27 and 3.14 rounds to 3
