Answer:
Area of the circular sidewalk = 405 m²
Step-by-step explanation:
Radius of the circular flower bed = 20 m
Area of the circular bed = πr²
Here r = radius of the circle
Area of the circular bed = π(20)²
= 400π square meter
Radius of the larger circle = Radius of the flower bed + width of the sidewalk
= 20 + 3
= 23 m
Area of the larger circle = π(23)²
= 529π m²
Area of the circular sidewalk = Area of the larger circle - Area of the flower bed
= 529π - 400π
= 129π
= 129(3.14)
= 405.06 square meters
≈ 405 square meters
Here you go:
1) 0.3 = 3/10
2) 0.125 = 1/8
3) 0.16 = 16/100 = 8/50 = 4/25
4) 0.1 = 1/10
5) 0.6 = 6/10 = 3/5
6) 0.2 = 2/10 = 1/5
7) 0.75 = 75/100 = 3/4

Answer:
F(5)=11.25
Step-by-step explanation:
I'm like 80% sure this is right, and I hope it helps.
First I did 9/4 which equals 2.25. and that would be F(1)
then added 2.25 to 9 which equals 11.25
multiplying 2.25 by 5 would also equal 11.25.
I did 5 because, on a number line, 5 comes after 4.
