Standard form: Ax + By = C
Equation: 12x + 15y = 120
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
Answer:
The coordinates for B' would be (-6,1) and the coordinates for C would be (-8,-6)
Step-by-step explanation:
Point A was translated 2 left and 1 down to point A'
B = (-4,2)
-4 - 2 = -6 and 2 - 1 = 1 so B' would equal (-6,1)
C = (-6,-5)
-4 - 2 = -8 and -5 - 1 = -6 so C' would equal (-8,-6)
6 times 10 is 60, keep in mind anything multiplied by 10, just add a 0 to it, and that is the answer.
