Answer:
20.36
Step-by-step explanation:
The area of the whole circle is pi*3.6^2 = 40.715 (rounded). However, the shaded portion is only half of the circle, since the arc is 180 degrees, so we divide this by 2 to get about 20.36.

Answer:
Step-by-step explanation:
a) Perform the following division problem using both long division and synthetic division to show that they both give the same answer. Show your work.
Attached in Figure 1
The quotient is: x^4+8
and the remainder is: 0
b) Second using a graphing calculator graph f(x)=x 5 - 8x 4 +8x - 64. Try Desmos.com
The graph is shown in Figure 2
c) Analyze the graph. Do you see a connection between the x - 8 and the graph? What is the connection?
The graph shows that the value of x is 8, for any value of y.
x-8 =0 => x=8 The value of x is 8 (The graph is attached in figure 3)
Both have same graph.
Given:
Arc length = 8 inches
radius = 3 inches
find the measure of the central angle.
Arc length = radius * central angle
central angle = arc length / radius
central angle = 8 inches / 3 inches
central angle = 2.667 (radian)
Central angle in degrees = 152.88°
Circumference of the circle = 2 * 3.14 * 3 inches = 18.84 inches
1 circle = 360° / 18.84 inches = 19.11° per inch
19.11° per inches * 8 inches of arc length = 152.88°
X=12
Substitute y with 0
Multiply both sides
0=-3/4x+9
0=-3x+36
3x=36
Divide by 3
It’s 12
