The area of a circle, given the circumference, is found using this formula:
A = C²/4π
Therefore,
A ≈ 451.93 cm²
break it up into simpler shapes. See the photo.
There is:
trapezoid
A = 0.5(3.2+6.5)4.5
= 21.825
triangle
A = 0.5(2.7)4.5
= 6.075
rectangle
A = 1.8(4.5)
= 8.1
Total Area = 21.825 + 6.075 + 8.1
= 36
Answer:
150
Step-by-step explanation:
the total angle of a flat line is 180
since one side is 30 180-30 is 150
