Answer:
The area of the shaded region is 125.664 square centimetre
Step-by-step explanation:
Area of the shaded region = area of the circle with radius 7 cm - area of the circle with radius 3 cm----------------(1)
<u>Step 1: Finding the area of the circle with radius 7 cm</u>
Area of the circle A = 
On substituting the value of the radius, we get
Area of the circle A =
Area of the circle A = 
square centimetre----------------(2)
<u>Step 2: Finding the area of the circle with radius 3 cm</u>
Area of the circle a =
On substituting the value of the radius, we get
Area of the circle a = 
Area of the circle a = 
square centimetre ----------------(3)
<u>Step 3: Finding the area of the shaded region</u>
Area of the shaded region = 
= 
= 125.664 square centimetre
Answer:
where are the correct statements?
Step-by-step explanation:
Answer:
Step-by-step explanation:
Notice that we already have the data sorted from least to greatest.
Now to find Q1 and Q3 we can use the following formulas
For a set of data ordered from least to greatest of the form 
Where n is the total number of data
In this case 
So:
Round the nearest whole and get:
For Q3 we have:
Round the nearest whole and get:
Answer:
<1 = 51 degrees
<2 = 61 degrees
<3 = 29 degrees
Step-by-step explanation:
Interior angles of a triangle: 180 degrees
180-68-61 = 51 degrees
<2 = 61 degrees (vertical angles)
<3 = 180-90-61 = 29 degrees
Slope-intercept form is y=mx+b, where m is the slope, and b is the y-intercept.
So, to convert x+6y=-2, you have to isolate y. Your first step is to move the x to the other side. To do this, you subtract 1x from both sides:
6y=-x-2
Your final step is to divide both sides by 6:
y=-1/6x+1/3
Hope this helps :-)
