It’s been awhile since I’ve done a problem like this but I believe it’s solved as below:
The area of a circle is equal to πr2. That will tell you the entire area of the circle. Then you would need to divide that by 2 to get the area of the 180° arc.
So, the area of this circle is 153.94 square meters. If you divide that by 2 (since 180° is half of a circle) you would get 76.97 square meters.
Step-by-step explanation:
65) Perimeter = 13 + 12 + 5 or 30 cm
Area= 5 x 12 / 2 or 30 cm^2
Perimeter formula: Add all the sides
Area formula ( triangle)= 1/2 bh
66) Perimeter = 8 + 4 + 7 + 3.5 or 22.5 ft
