Circumference = 2(Pi)r
r = 6
(2)(3.14)(6) = 37.68 m
Answer:120
Step-by-step explanation:
Answer:
5.5 hours
Step-by-step explanation:
For every 1 hour, there is a 0.8 degrees Celsius drop in temperature.
Let "t" represent the total amount of temperature dropped.
Let "h" represent the number of hours
The given scenario can be represented with the equation below:
To find the number of hours (h), it takes for the temperature to decrease by 4.4 degrees Celsius, plug in the value of t in the equation, and solve for h.
Divide both sides by 0.8
It would take 5.5 hours for the temperature to decrease by 4.4 degrees Celsius.
Answer:
A. lw = (x+6)(x -6); 133 square feet
Step-by-step explanation:
If x is the original length (in feet), when the length is increased by 6 feet, it can be represented by (x+6).
If x is the original width, when it is decreased by 6 feet, it can be represented by (x-6).
The area is the product of length and width, so the new area is ...
lw = (x+6)(x-6)
___
Since the original side is 13 ft, the new length is 13+6 = 19 ft, and the new width is 13-6=7 ft. The area is ...
(19 ft)(7 ft) = 133 ft²
