Answer:
The area of the roof: ≈2287.44 ft^2, the lateral area of the roof:≈1580.58 ft^2
Step-by-step explanation:
The area of the roof is computed by the equation of the area of a cone:
A = πr(r +
)
(r: radius, h: height, πr^2 is the area of the base of the cone, πr
is the lateral area of the cone). So:
A =
≈ 2287.44 ft^2.
As I stated earlier, the lateral area of the roof can be computed:
A
=
≈ 1580.58 ft^2.
Answer:
slope is undefined
Step-by-step explanation:
Calculate the slope m using the slope formula
m = 
with (x₁, y₁ ) = (1, 2) and (x₂, y₂ ) = (1, - 3)
m =
= 
Since division by zero is undefined then the slope of the line is undefined
Answer:
-88
Step-by-step explanation:
Because when you all ad it down you get -96 and then -8= -88
I believe it is 1500
(1920 - 420)
