<h2>63.6 cm</h2><h2 />
Cut diameter in half to find radius
9/2 = 4.5
radius = 4.5
This is the formula for area of a circle:
pi * radius^2
pi * 4.5^2
20.25pi
Now find pi:
20.25 * pi = 63.6
Answer:
63.6 cm is the area

Answer:
Step-by-step explanation:
Given
Rate of Long family's sprinkler is 25 L/hr
rate of Harris family's sprinkler is 35 L/hr
Total time for which sprinkler is used =55 hr
Let long family run their sprinkler for x hr
therefore Harris family time=55-x
Total volume collected=1625 L
thus

25x+1925-35x=1625
1925-1625=10x
300=10x
x=30 hr
long family used for 30 hr and Harris family used for 20 hr
Answer:
y = -5x - 1
Step-by-step explanation:
Let the equation of a line parallel to the given line is,
y - y' = m(x - x')
Where m = slope of the line
And line passes through (x', y')
Equation of a line has been given as,
5x + y = 4
y = -5x + 4
Slope of this line = -5
By the property of parallel lines "slope of the parallel lines are same",
m = -5
Parallel line passing through (-1, 4) and slope 'm' = -5 will be,
y - 4 = -5(x + 1)
y - 4 = -5x - 5
y = -5x - 5 + 4
y = -5x - 1
Therefore, equation of the parallel line will be,
y = -5x - 1
