We know that, Area of a Circle is given by : πR²
Where : R is the Radius of the Circle.
We can Notice that : The Given Figure is One - Fourth of the Circle with Radius 'R'

We can Notice that : The Quarter of the Circle is divided into 3 Equal Parts and The Shaded Region is One of the Equal Part.


Answer:
w = -16.
Step-by-step explanation:
14 = -7/8w
To isolate w on the right side we multiply both sides by -8/7:
14 * -8/7 = -7/8 * -8/7 w
-16 = w.
Convert the yards to feet.
1 yard = 3 feet.
140 yards x 3 feet per yard = 420 feet.
90 yards x 3 feet per yard = 270 feet.
Area = 420 x 270 = 113,400 square feet.
Refer to the diagram below for the sketch of the position of the mirror, Michelle, and the flagpole.
Using similar triangle concept, to find the height of the flagpole, we first need to find out the scale factor of the horizontal distance.
We write this as ratio
Mirror to Michelle : Mirror to Flagpole
12ft : 48ft
1 : 4
So the ratio of the height is
Michelle : Flagpole
1 : 4
5ft : 20ft
Answer: A
Geometric progresión:
we can calculate any term, using this rule:
an=a₁*r^(n-1)
a₁=the first term
r=the common ratio
a₆=128
r=2
an=a₁ * r^(n-1)
128=a₁ * 2⁶⁻¹
128=a₁ * 2⁵
128=a₁ * 32
a₁=128/32=4
Solution: a₁=4
