Solving the area of the circle A = π × 2^2 A = 12.57 halve /2 = 6.29 area of the square = 4*4 16 subtract area of half circle from area of square 16 - 6.29 = 9.71
You first want to find the area of the semi circle by using the formula A=πd ÷ 2 + d Once you plugged everything in, it should equal 10.28 you then want to find the area of the square by using the formula A=bh Once you plugged everything in, it should equal 16 The last step is to subtract the two numbers, which equals 5.72ft²
If a line is parallel to another line,Then the gradients are the same.So m=4 .Using general formula for str8 line, y=mx+c sub in coorfinates (1,13) So C=9.
