Answer:
6,280 ft³
Step-by-step explanation:
To find lateral surface area, use the formula L = 2rh, then plug in the values:
L = 2(3.14)(25)(80)
L = 12,560 ft³
Since its a half cylinder, we have to divide this by 2:
12,560/2 = 6,280
So, the lateral area of the roof is 6,280 ft³

The solutions to the equation -2x = 2^x are (1,2) and (2,4)
<h3>How to determine the solutions?</h3>The attached graph represents the missing part of the question
The equations are given as:
f(x) = -2x
g(x) = 2^x
The solution to -2x = 2^x is the points where the graphs of f(x) and g(x) intersect
From the attached graph, the points of intersection are:
(1,2) and (2,4)
Hence, the solutions to the equation -2x = 2^x are (1,2) and (2,4)
