Answer:
Step-by-step explanation:
Given
Area of Sector : Area of Circle = 3 : 5
Required
Determine the central angle
The question implies that
Multiply both sides by 5
Multiply both sides by Area{circle}
Substitute the areas of sector and circle with their respective formulas;
So, we have
Divide both sides by
Multiply both sides by 360
Divide both sides by 5
Hence, the central angle is 216 degrees
Answer:
5(7xy + 5x) , 5x(7y +5)
Step-by-step explanation:
Answer:
The one with the higher amount they put away
Step-by-step explanation:
Answer:
deal with the rectangle first A = l X w
4 X 12 = 48 squared cm
semi circle
Area of a circle πr^2
12/2 = 6, radius = 6
π6^2 = 113.097335
113.097335/2 = 56.5486677
56.5 + 48 = 104.5 squared cm
