The area of the shaded region:
A = r ² π - a²
where: r = d/2 = 7√2 / 2
A = ( 7√2 / 2 )² · 22/7 - 7²
A = 49 · 2 / 4 · 22/7 - 49
A = 49/2 · 22/7 - 49
A = 7 · 11 - 49
A = 77 - 49
Answer: A (shaded) = 28
Answer:
parallel lines are lines that are always the same distance apart. they never intersect.
perpendicular lines are lines that intersect at a right angle (90 degrees)
Answer: An arc can be measured either in degree or in unit length. A
arc is a portion of the circumference of the circle which is
determined by the size of its corresponding central angle.
Step-by-step explanation:
create a proportion that compares the arc to the whole circle first
in degree measure and then in unit length.
(measure of central angle/360 degrees) = (arc
length/circumference) arc length = (measure of central angle/360
degrees)(circumference)
Answer:
The constant proportionally of the graph is:
Step-by-step explanation:
We know that when 'y' varies directly with 'x', we get the equation
y ∝ x
y = kx
k = y/x
here 'k' is called the constant of proportionality.
From the graph, it is clear that:
at x = 0.5, the value of y = 4
so substituting x = 0.5 and y = 4 in the equation
k = y/x
k = 4/0.5
k = 8
at x = 1, the value of y = 8
so substituting x = 1 and y = 8 in the equation
k = y/x
k = 8/1
k = 8
Therefore, the constant proportionally of the graph is:
