Answer:
5.38516480713
Step-by-step explanation:
a^2+b^2=c^2
5^2+2^2=c^2
25+4=c^2
c^2=square root of 29
c=5.38516480713
Answer:
The lateral area of the pipe is 942 sq ft.
Step-by-step explanation:
A pipe can be modeled as a cylinder prism.
The lateral area of a cylinder prism can be expressed as the product of the length by the perimeter of the section.
We start by calculating this perimeter.
As the diameter is 25 ft, the perimeter of the section can be expressed as:
![P=\pi D=3.14\cdot 25=78.5](https://tex.z-dn.net/?f=P%3D%5Cpi%20D%3D3.14%5Ccdot%2025%3D78.5)
Then, to know the lateral surface we multiply this perimeter by the length of the pipe (12 ft):
![A=P\cdot l=78.5\,ft\cdot 12\,ft=942\,ft^2](https://tex.z-dn.net/?f=A%3DP%5Ccdot%20l%3D78.5%5C%2Cft%5Ccdot%2012%5C%2Cft%3D942%5C%2Cft%5E2)
The lateral area of the pipe is 942 sq ft.
The centre of this circle is at 12
