Answer:
<h2>The answer is option A</h2>
Step-by-step explanation:
Area of a circle = πr²
where
r is the radius of the circle
From the question
r = 15.2 cm
The area of the circle is
A = (15.2)²π
= 231.04π
= 725.833566685386...
We have the final answer as
<h3>725.8 cm²</h3>

Step-by-step explanation:
10000 different phone numbers are possible for a particular prefix if repetion of digits is allowed
5040 different phone numbers are possible for a particular prefix if repetion of digits is not allowed
<em><u>Solution:</u></em>
Given that,
A seven digit phone number consists of a three-digit prefix followed by four digits
We have to find the different phone numbers are possible for a particular prefix
For a paricualr prefix, there are four digits
Total numbers from 0 to 9 are 10
Therefore,
Different ways for phone number for particular prefix:
If repetition is allowed:
Different ways = 10 x 10 x 10 x 10 = 10000 ways
If repetition is not allowed then:
Different ways = 10 x 9 x 8 x 7 = 5040 ways
