A circular sector is the area between two radii of a circle and the arc between them.

The area is indeed given by

pi*r^2*(arc angle/360)

=pi*10.5^2(118/360)

=36.1375 pi cm^2

=113.529... cm^2

Therefore your answer is correct, to the first decimal place.

Perhaps you can check if the question specifies a different accuracy for the answer, or a different value of pi to be used.

How much time will it take for the plane to land?
serious [3.7K]

Answer:

Again assuming we're cleared for immediate take off, it takes around 20 minutes to climb to cruise altitude, at an average ground speed of (say) 200 knots. This means we've covered about 70 miles, which the cruising aircraft would have covered in just over 10 minutes. So this final phase has cost us another 10 minutes

Identify the vertex for the graph of y = −3x^2 + 6x − 4
algol [13]

Answer:

the vertex is (1,-1)

Step-by-step explanation:

y = −3x^2 + 6x − 4


the vertex is at

h= -b/2a  where ax^2 +bx+c

h= -6/2(-3)

h= -6/-6

h=1

substitute this in to find the y value

y = -3(1)^2 +6(1)-4

y = -3+6-4

y = -1

the vertex is (1,-1)
