Answer:
Area of the blue border is 100.544 ft²
Step-by-step explanation:
What is the area of the blue border?
Area of a Circle = πr² , where π = 3.142
Where: Outer diameter = 12 ft ==> (half of diameter) Radius (r₁) = 6 ft
Inner diameter = 4 ft ==> (half of diameter) Radius (r₂) = 2 ft
The blue border is the space between the edge of the rug and the inner red circle.
The area of the blue border = Area of outer circle - Area of the inner circle
Area of Outer Circle = πr₁² = 3.142(6)² = 113.112 ft²
Area of Inner Circle = πr₂² = 3.142(2)² = 12.568 ft²
The area of the blue border = 113.112 - 12.568
= 100.544 ft²
Answer: Yes! You are correct.

The three angles of a triangle equal 180
Third angle = 180 - 31.8 - 89.8 = 58.4
Answer: 58.4
Answer:
Simple random sampling
Step-by-step explanation:
The type of sampling used here is simple random sampling(SRS) because SRS is defined as the sampling technique where a group of subjects known as sample are selected for study from a larger group known as population. Thereafter, each individual will be entirely chosen by chance and then each member of the population will have an equal opportunity of being included in the sample.
Thus question given corresponds to this definition.
Part A.
32'1/4÷1/8=258
1 team has 8 people, we currently have 32'1/4 teams, so how many people do we have? We have 258 people.
you can adjust this any way you want. you can say. if we have 258 people, we can make 32'1/4 teams of 8 people. and so on...
Part B.
32'1/4(teams)×8(people per team)=258 people
Part C.
you can explain this from what I said in Part A and Part B.
but 32'1/4 is 1/8 of 258
