We know that to find the area of the entire circle, we are going to use the equation:
And we know that the diameter is 12. To find the radius, we divide the diameter by 2, so 12/2 = 6. So the radius is 6.
Now we can use this radius in the equation:
Since all of the angles of each section are equal, we can assume that each of the sections has an equal area. There are 5 sections, so we need to divide by 5 to find the area of each section:
Each section has an area of or, using 3.14 for pi, .
Since we are told to find the area of the blue sections, we know that there are 2 sections that are blue. So we need to multiply the area of each section by 2, to find the area of two of the sections:
Therefore, the answer is C) 45.2 .
Answer:
-12 and -5
Step-by-step explanation:
a+b=-17
b-a=7
b=7+a
a+7+a=-17
2a+7=-17
2a=-17-7
2a=-24
a=-12
-12+b=-17
b=-17+12
b=-5
so a and b are -12 and -5 respectively
