Answer:

Step-by-step explanation:
The <u>total area</u> of the circle is given by:

where
is a constant 
and
is the radius: 
Thus the total area of this circle is:

We want only the area of the arc that measures 50°. For this we must remember that the arc of the total circle is 360°.
Thus, we want 50° out of the 360° degrees in the circle. For this, we divide the total area by 360 and then we multiply by 50:

the area of the sector to the nearest tenth is 
Answer:
Step-by-step explanation:
What you do first is multiply -4 and -5 which gives you 20 (two negatives gives you a postitive answer.) Then add 18 which gives you 38.
Answer: 38
It's -13/42. You've gotta calculate the product then subtract fractions
To solve this problem, you read the problem backwards and to the opposite of that function.
- if it says double --> divide by 2 22 / 2 = 11
- subtract by 19 --> add 19 11 + 19 =30
- multiply by 5 --> divide 5 30 / 5 = 6
Thus the number that is thought of is 6
Hope that helps!
