Step-by-step explanation:
The delivery radius which will allow the pizza restaurant to deliver to approximately 20,000 people is 2. 5 miles
<h3>What is population density?</h3>
Population density can be defined as the number of individuals within a species in a specific geographic area.
The formula for population density is expressed as;
Population density = Number of people/Land area
Where;
- Number of people = 20000
- Population density = 1000
Land area = 20000/ 1000
Land area = 20 square miles
But ;
Area = πr²
Substitute the value of area in the formula
20 = 3. 142 × r²
r² = 20/ 3. 142
r² = 6. 37
r = √6. 37
r = 2. 5 miles
Thus, the delivery radius which will allow the pizza restaurant to deliver to approximately 20,000 people is 2. 5 miles

Answer: He makes $111.80 in 2 days.
Step-by-step explanation:
Since we have given that
Amount he makes in 3 days = $167.70
Number of days = 3
We need to find the amount he makes in 2 days.
We will use "Unitary method" to find the amount s in 2 days.
In 3 days , amount = $167.70
In 1 day, amount is given by
In 2 days, amount is given by
Hence, he makes $111.80 in 2 days.
