divide both sides by 7 to get x alone
84/7 = 12
B.12
When finding best estimates, it is best to round each number based on how many digits the number holds. In this case, the dominant place of 289 is the hundreds place, which means this should be rounded to 300. The dominant place of 7 is 10. Therefore, you multiply these two numbers in order to get your best estimate, which is 3000 (overestimate).

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.
