Answer:
Step-by-step explanation:
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.
Answer:21/2
Step-by-step explanation: first you subtract 3x from both sides ending up with 2x on the left side. 2x-2= 9+10. You’ll then combine like terms adding 9 and 10 having 2x-2=19 You then add 2 to both sides. 2x=21 then dived by 2 on both sides. It won’t simplify so the answer is x=21/2

Answer:
521,400 meters squared
Step-by-step explanation:
With the 1cm = 100m scale
6.6 cm = 660m
7.9 cm = 790m
Area = 660 x 790 = 521,400 meters squared
