Answer:
Rate of the current: 19 kilometers per hour
Rate of the boat in still water: 80 kilometers per hour
Given:
Radius of circle = 12 units
Area of sector = 24π sq. units.
Central angle = x
To find:
The value of x.
Solution:
We have,
We know that, area of a sector is
Where, 
is central angle, r is radius.
Multiply both sides by 360 degrees.
The value of x is 60 degrees.
Therefore, the correct option is A.
Step-by-step explanation:
8 times 12 is 96
10 times 15 is 150 add them together and get 246
Answer:
((3 / 14) * 3) / 14 = 9 / 196
Step-by-step explanation:
Reduce 9/196 to lowest terms 9 196 is already in the simplest form. It can be written as 0.045918 in decimal form (rounded to 6 decimal places).
45 because 180 divided by 2=90 and 90 divided by 2= 45 because she needs area which is length times width= area and area divided by length or width= the other
