Answer:
- 113.0 cm²
- 2464.0 in²
- 95.0 ft²
Step-by-step explanation:
1. The area of a circle is given by the formula ...
A = πr² . . . . . where r is the radius
The radius is shown as 6 cm, so the area is ...
A = (3.14)(6 cm)² = 113.0 cm²
__
2. The radius is shown as 28 in. We note that this is a number divisible by 7, so we choose 22/7 for π.
A = (22/7)(28 in)² = 2464 in² . . . . see comment
__
3. The radius is half the diameter, so is 11/2 = 5.5 ft. Then the area is ...
A = (3.14)(5.5 ft)² = 95.0 ft²
_____
<em>Additional comment</em>
If you use a more exact value of π for problem 2, the area is 2463.0 in². If you use 3.14 as the value of π, the area rounds to 2461.8 in². For these values of pi (3.14 or 22/7), the answer is only good to about 3 significant digits. 2464 has more significant digits, so digits beyond the first 3 may be in error.

Step-by-step explanation:
Answer: a<b
Step-by-step explanation:
Given statement: "a number <em>a</em> is always less than another number <em>b."</em>
<em />
We use "<" or ">" sign to show less than or more than comparison in a mathematical statement.
If <em>a</em> is less than <em>b </em>then it can represented as
<em>a < b</em>
The expressions expresses the relationship between <em>a</em> and <em>b</em> would be:
<em>a < b</em>
