Bye yw!
Hey there!
1. Arc IJ = 62
1/2(360 - 2(78 + 40)) = 62
2. Arc WY = 103
50 + 53 = 103
3. Arc DEG = 204
70 + 77 + 57 = 204
4. Use pythagorean theorem
12.4^2 = x^2 + 11.5^2
x = 12.3
5. Use pythagorean theorem
x^2 = 5.2^2 + 8.4^2
x = 9.9
6. Use pythagorean theorem
18.1^2 = 10.1^2 + x^2
x = 15.1
7. Use the formula for the area of a circle
A = pi x (10^2)
A = 100pi
A = 314.2yd^2
8. Use the formula for the area of a circle
A = pi x (5.4^2)
A = 29.16pi
A = 91.6m^2
9. Use the formula for the circumference of a circle
C = 2 x pi x 4
C = 8pi
C = 25.1ft
10. Use the formula for the circumference of a circle
C = 2 x pi x 3
C = 6pi
C = 18.9yd
11. Use the standard equation of a circle
4 = (x - 15)^2 + (y - 8)^2
12. Use the standard equation of a circle
122 = (x + 1)^2 + (y - 3)^2
Hope this helps!! :)

Answer:
18.135
Step-by-step explanation:
30*9.75=292.5
6.2%*292.5=18.135
5): Rectangular Flowerbed
Total Area:
14m * 10m
140m^2
Flower Bed Area:
10m * 6m
60m^2
Area of Path:
140m^2 - 60m^2
Answer ======> 80m^2
4): Area of Parallelogram: 4.5m^2
Area = B * H =====> 2.5m * 1.8 ====> 4.5m^2
b Base of the parallelogram ====> 2.5m
h Height of the parallelogram ======> 1.8m
Answer ======> Area ======> 4.5m^2
Hope that helps!!!! Numbers 5 and 4 is done for you!!!!
