Answer:
The total cost is <em>28.26.</em>
Step-by-step explanation:
The radius of the birdbath is <em>1.25 feet.</em>
The cost per foot is <em>3.6</em> .
<em>The formula for perimeter of circle is given by,</em>
<em>= 2πR , where R is the radius of circle.</em>
Inserting the above value of radius in the equation above,
circumference = 2(π)(1.25) = 2(3.14)(1.25) = 7.85
Thus the total cost is,
= (7.85)(3.6) = 28.26
Answer:
A) speed = 10.5 miles per hour
B) Time taken by him = 1.714 hours
C) Distance = 10.5 mph × 7 hours = 73.5 miles
Step-by-step explanation:
Given as :
The distance cover by David = miles = 5.25 miles
The time taken by David = hours = 0.5 hours
Let the speed = x mile per hour
So, Distance = Speed × Time
A)or, Speed =
Or, Speed =
∴ speed = 10.5 miles per hour
<u>B) Again The Distance cover by him = 18 miles</u>
SO, with speed 10.5 miles per hour
The Time taken by him = hours
Or, Time taken by him = hours
∴ Time taken by him = 1.714 hours
<u>C) Again the Time taken by him = 7 hours </u>
So, Distance cover by him with speed 10.5 mph
Or, Distance = 10.5 mph × 7 hours = 73.5 miles
A) speed = 10.5 miles per hour
B) Time taken by him = 1.714 hours
C) Distance = 10.5 mph × 7 hours = 73.5 miles Answes
