Answer:
540 degrees
Step-by-step explanation:
Since you already know the radius multiply it by itself(20*20=400)then multiply that amount by 3.14.(formula: 3.14*(radius*radius)
Answer:
To find the perimeter, add together the lengths of the sides. Start at the top and work clockwise around the shape. Area of Polygon = (Area of A) + (Area of B) To find the area, divide the polygon into two separate, simpler regions.
Step-by-step explanation:
The answer is:
545>322
540 <997
The answer: " k = -10 " .
__________________________________________
Given: (- 6/5) k = 12 ; Solve for: "k" ;
__________________________________________
Multiply each side of the equation by "5" ; to get rid of the "fraction":
5* (-6/5) k = 12 * 5 ;
to get:
- 6 k = 60 ;
Divide each side of the equation by "-6" ;
________________________________________
- 6 k / 6 = 60 / 6 ;
to get:
-1 k = 10 ;
_______________________
Divide each side of the equation by "-1" ;
to isolate "k" on one side of the equation ; and to solve for "k" ;
________________________
- 1 k / -1 = 10 / -1 ;
________________________
to get: k = -10 .
