Find the area of each shape and add.Let's start with the first semi-circle(half-circle) If the area of a circle is πr² , then the area of a semi-circle is 1/2πr² where is 22/7 or 3.14, and r is the radius which is 1.8 meters A=1/2πr² A=1/2*22/7*1.8*1.8 A=5.09 m²(rounded to nearest hundredth) Since the semi-circles are two and have the same radius, multiply the area of the first one by two or go through the same process again. So 5.09 *2=10.18meters square is the area of the two semi-circles Now, let's find the area of a rectangle which is length times width, where length is 6 meters and width is (1.8+1.8, because 1.8 is half the width)=3.6 meters A=l*w A=6*3.6 A=21.6meters square Therefore the area of the shape is 10.18m²+21.6m²=219.888m²
Since it's parallel, then the slope is the same use the point slope formula and plug in the slope and point y-y1=m(x-x1) y-4=-4(x+2) y-4=-4x-8 y=-4x-4 this is in slope intercept form
