Answer: 900 degrees
Step-by-step explanation:
The formula for the sum of the interior angles is (n-2)*180 where n is the number of sides.
In this case, there are 7 sides so the sum of the interior angles would be
(7-2)*180
= 5*180
= 900 degrees
225/3 = 75
75 x 5 = 375
Hope this helps.
Answer:
Step-by-step explanation:
r = 12
V = 4*pi * r^3 / 3
V = 4 * 3.14 * 12^3 /3
V = 4 * 3.14 * 1728 / 3
V = 4 * 5425.92 /3
V = 21703.68/3
V = 7234.56

Answer:
degrees Fahrenheit
Step-by-step explanation:
Let 
be temperature.
at 3:00PM: 
degrees.
Every hour, the temperature falls by 
degrees per hour for the next four hours. Let's multiply 2.5 by 4 to find out the total temperature drop in four hours.
In four hours, the temperature dropped 10 degrees. Since it is getting colder, let's subtract this from the original 5.5 degrees to get the temperature at 7:00PM.
The temperature at 7:00PM was -4.8 degrees Fahrenheit.
