Answer:
106.81
Step-by-step explanation:
first convert diameter to radius
- radius = diameter / 2
- radius = 34/2 = 17
now find circumference
- circumference = 2πr
- circumference = 2π(17) = 106.81
r = radius
“C” Os the correct answer
An equation in point-slope form is
y - y1 = m (x - x1)
Your point is (7,6) and your slope is 2
y1 is the y coordinate of your point (in this case 6)
x1 is the x coordinate of your point (in this case 7)
m is your slope (in this case 2)
Now you just have to plug these numbers in:
y - 6 = 2 (x - 7)
Answer: The answer is 284.
Step-by-step explanation:
The area of the garden is an annulus whose,
Outer diameter = 18 ft
Inner diameter = 18 ft - 2*3ft = 12 ft
Therefore,
Outer radius = 18/2 = 9 ft
Inner radius = 12/2 = 6 ft
Area of garden = Area of annulus
Area of garden = π*(9 ft)2 - π * (6 ft)2
Area of garden = 142
Given:
2 flowers are planted per square foot.
Therefore for 142 ft2,
Number of flowers required = 2*142 = 284
The answer is 284.
