The answer is a because you multiple times and divided
Answer:
45.86 ft²
Step-by-step explanation:
Circumference of a circle = 2 * pi * r
Circumference = 24
24 = 2 * 3.14 * r
24 = 6.28r
r = 24 / 6.28
r = 3.8216 ft
Approximate area of garden :
Area of circle :
pi * r^2
Area = 3.14 * 3.8216^2
Area = 45.8585273984
Area = 45.86 ft²
All the angles should add up to 360°.
8x+10x+9+21x-12+90=360°
Group like terms together.
So,8x+10x+21x+9+90-12=360
39x+87=360
39x=360-87
39x=273
x=7
