The area of one fence post whose radius 1/2 ft and height 5 ft. is 164.85 sq. ft.

<h3>What is Surface Area?</h3><h3>Surface area and volume are calculated for any three-dimensional geometrical shape. The surface area of any given object is the area or region occupied by the surface of the object. </h3>

Area of one fencepost = Curved surface area + Area of Top surface

          = 2πrh + πr²

                                      = 2(3.14)(1/2)5 + (3.14)(1/2)²

                                      = 16.485 sq ft

Total area of 10 fencepost =  10 X 16.485 = 164.85 sq ft

Thus, the area of one fence post is 164.85 sq. ft.

How do You supposed to do this i need many method to do it.
defon
I like the substitution method. Which is when you make one equation equal only x or y and plug it into the other equation)

There is also the graphing method. If you graphed it, it might not be quite as accurate (at least on hand, on computer you would be pretty exact)

Then there is the elimination method. You multiply one of the equations by a coefficient so that you can eliminate x or y from the equation.
