The perimeter of a circle is:
P = 2 π r
The distance from the center of the pool to the fence is actually a radius of the circle:
r = 15 ft
P = 2 * 3.14 * 15
P = 94.2 ft² ≈ 94 ft²
Answer:
2 tons of dirt per hour
Step-by-step explanation:
helpful to know: 1/6 hours = 10 minutes
you can create a proportion to find unit rate by using (tons of dirt ÷ time)
we'll use 'd' to represent amount of dirt and use minutes
1/3÷10 = d/60
1/3÷10 = 1/3 × 1/10 = 1/30
we now have:
1/30 = d/60
we can cross-multiply to get:
30d = 60
d = 2
C becuase it makes the most sense
For a 45-45-90 triangle if the sides rae x then the the hytponuse is x√2
(x is the missing side)
5. 10=x√2
10/√2=x
rationalize denom, times top and bottom by √2
10√2/2=x
5√2=x=XY
6. 12√2=YZ
7.
7√2=XZ
8.
7*2=14=XZ
for 30-60-90
the side oposite the 30 deg is x
side oposite 60 is x√3
side oposite right angle is 2x
hyptonuse is oposite right angle
20=2x
10=x=shorter leg
shorter leg is 10 units
the hyptonuse
m x 7 = 28
Solve for m by dividing both sides by 7:
m = 4
