Answer:
5
Step-by-step explanation:
Let's work from the middle of the equation to the outside of it. Our first part of the equation is 3+4, which equals seven, so we have the equation:
81-2[5(7)]
Then, we multiply 5 and 7, which is 35, so we get the equation:
81-2[35]
Then we have -2 outside of the brackets, so we can multiply -2 and 35, which is -75, so we have the equation:
81-75
Which is 5.

Answer:
The area of the sector BOC is A' = 31.4
Step-by-step explanation:
Radius of the circle = 10 cm = 0.1 m
Angle of sector = 36°
Area of the circle A =
A = 3.14 × = 0.0314
Now area of the sector BOC is
A' = 0.00314 = 31.4
Therefore the area of the sector BOC is A' = 31.4
