5x can be written as x + x + x + x + x
Answer:
6,280 ft³
Step-by-step explanation:
To find lateral surface area, use the formula L = 2
rh, 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
Answer:
0
Step-by-step explanation:
