Answer:
Area of second circle = 56cm² +
Area of second circle = 2179.71cm²
Step-by-step explanation:
let the radius of the small circle be r and that of the big circle be R
Area small circle =
Area Big circle =
Area Big circle - Area small circle = 56cm²
- =56cm²
The second circle is the bigger circle.
Area of second circle - =56cm²
Area of second circle = 56cm² +
r =26cm
Area of second circle = 56cm² +
Area of second circle = 56cm² +
Area of second circle = 56cm² +
Area of second circle = 56cm² + 2123.71
Area of second circle = 2179.71cm²
<span>On a certain survey it says:
12 out 15 people in the United States prefer eating at the restaurant rather
than home.
To know how many percent is this.
=> 12 / 15
=> 0.8 which is also 80%
Now, the 80% of the those people in the
survey is 400.
Find the total number of people who took
the survey.
Since we already have the 80%, we need to find the number of 20%
=> 400 x 20%
=> 400 x .20
=> 80
=> 400 + 80
=> 480 => the total number of people who took the survey
