Answer:
322.28
A
Step-by-step explanation:
Area of the rectangle
L = 30
W = 21
Area = 30 * 21
Area = 630
Area of the circles
Radius = 7 m
Area = pi r^2
Area = 3.14 * 7^2
Area = 153.86 m^2
Area of both circles = 307.72
Area of the Shaded Region
Area of shaded region = area of the rectangle - area of 2 circles.
Area of Shaded Region = 630 - 307.72
Area of Shaded Region = 322.28
1: yes it is a polygon because it has more than 3 straight sides
2:it is called a hexagon because it has six sides
3:they are all equal
4:concave because all angles are less than 180°
5: regular because all angles are escualos
To find slope you need to use the coordinates of two points on the line. If the coordinates are (x1, y1) and (x2, y2) do y2-y1 / x2-x1 to find the slope.
So far in the equation of a line, y=mx+b, you have the "m" which is the slope.
Plug in the slope, and the x and y values from one of the points and solve for b, which is the y intercept.
Here's an example if the coordinates are (1,4) and (2,6):
6-4/2-1 = 2/1 = 2
The slope is 2.
y = 2x + b
4 = 2(1) + b
4 = 2 + b
4-2 = 2-2 + b
2= b
The full equation is y = 2x + 2
