Answer:
16 ft²
Step-by-step explanation:
Since we're told that 2 ft diameter was cut of the board. We use the formula for hollow circle to find the area.
Area of remaining body = area of full body - area of removed body.
Area = πd²/4
Area of remaining body = (π * 5²)/4 - (π * 2²)/4
Area of remaining body = 19.64 - 3.142
Area of remaining body = 16.49 ft²
Therefore, the remaining area is then calculated into 16 ft²
The decimal to 690 it’s going to be 6.9
-8,-9 because reflecting over a certain axis means you multiply the number in the coordinate pair of that axis by -1
A vertical line on a sheet of lined graph paper is a vertical axis (normally called the X axis) that denotes everything to the left of the line is negative and everything to the right is positive. A horizontal line on that graph paper (normally called the Y axis) denotes everything below the line is negative and every thing above is positive. Each axis is graduated in scale. The equation X=Y has no single answer, but we can plot a locus of points on your graph by assigning values to X ( or Y) and create a diagonal line which passes thru the origin (where the lines cross) that denotes all possible answers to the equation that exist within the limits of the graph paper. Every equation will plot a locus of points.
