That's a part of a circle that has a radius of 9 inches.
Area of any circle = (pi) x (radius)²
Area of the full circle that this is a piece of = (pi) x (9)² = (81 pi) square inches.
That's the whole circle. How much of the whole circle is in the picture ?
A whole circle has 360 degrees in the middle. This piece has 105 degrees in the middle.
This piece is ( 105/360 ) of the whole circle.
So the area of the piece is (105/360) x (81 pi) = <u>74.22 square inches</u> (rounded)
Answer:
The answer is 23.
Step-by-step explanation:
You need to multiply and divide.
Answer:
- 3x² + x + 5
Step-by-step explanation:
- 2x² + 4x + 5 - (x² + 3x) ← distribute by - 1
= - 2x² + 4x + 5 - x² - 3x ← collect like terms
= - 3x² + x + 5
Answer:
All 13,000 titles in the bookstore
Step-by-step explanation:
We are given the following in the question:
The bookstore carries 13,000 titles.
Sample size, n = 200
Population and sample:
- Population is collection of all the possible observation of an event.
- A sample is a part of a population and is always smaller than a population.
- Sample statistics are used to estimate the population parameters.
Population of interest:
All 13,000 titles in the bookstore
Sample:
Sample of 200 books that is used to approximate the mean price of all 13,000 titles in the bookstore.
