Answer:
103.62 cm squared :)
Step-by-step explanation:
To solve this problem, lets start with the grey area only and essentially we want to treat it like it's own circle. So the formula for circular area is A=pi times r²
so for the radius of the grey region, we will simply add 3 and 4 cm.
3+4=7cm
Then we can plug that into the area equation, which is:
A = (3.14)(7²)
Solve for that and we should get 153.86 cm²
We'll hold onto that for now while we solve for the white circle next:
A = (3.14) (4²)
A = 50.24cm²
Lastly, let's bring back the grey area we found earlier, and subtract the white area from it:
153.86 - 50.24 = 103.62 cm²
hope this helps and good luck~
Answer:
Angle 5 = 37°
Angle 8 = 143°
Step-by-step explanation:
Angle 2 = Angle 8
Reason : Alternate exterior angles are equal.
Therefore,
Angle 8 = 143°
Angle 5 + Angle 8 = 180°
Reason : Angle 5 & 8 are in a linear pair.
Angle 5 + 143° = 180°
Angle 5 = ( 180 - 143 )°
Angle 5 = 37°
