Answer:
C) 
Step-by-step explanation:
The formula for area is
A=pi * radius ^2
If the diameter is 40, the radius is 20
Therefore

Temperature goes down up to 10° Celsius during the night.
Given that;
Temperature drop from 5º Celsius to -5º Celsius
Find:
Change in temperature in Celsius
Computation:
Change in temperature = Initial temperature in Celsius + Final temperature in Celsius
Change in temperature = 5 - (-5)
Change in temperature = 5 + 5
Change in temperature = 10° Celsius

2(area of s) + 2(area of f) + 2(area of ff) if s = side and f= opposite faces and ff = opposite faces.
2(4x3) + 2(3x10) + 2(4x10)=
24+60+80=
164 in squared
Answer:
y = 3x - 5
Step-by-step explanation:
I used my calculator so that it would be faster.
But if you want work you have to find the slope then plug in.
To find the slope use points (1, -2) and (2, 1) use this formula 
Plug the points in 
So your slope is 3
NOw Plug In (1, -2)
-2 = 3(1) + b (b represents the y- intercept)
-2 = 3 + b (subtract 3 on both sides)
-5 = b
The final equation is y = 3x - 5
Hope this helps ya!!
I’m trying to figure this out too
