The area of a circle is:
A=πr^2, area=pi times the radius squared...
In this case the radius, r, is equal to 6mm so
A=π(6^2) mm^2
A=36π mm^2
So the area is 36π mm^2, where the units are square millimeters
Answer:
12 is 52 i think. i am not sure about 11.
Step-by-step explanation:
im so sorry i know 11:(
I hope this helps on 12 tho
84-14=70/2=35+14=49+35=84
The numbers are 49 and 35
To solve the problem, we need to use the relation between the angles to find a relation involving x. Then we need to solve for x and use that value to determine the measure of the desired angle.
The diagram shows you ...
... ∠KIJ + ∠JIH = ∠KIH
The problem statement tells you ∠KIJ = ∠JIH, so we can substitute ∠JIH in the above equation to get
... ∠JIH + ∠JIH = ∠KIH
... (4x+3) + (4x+3) = (12x)
... 8x +6 = 12x
... 6 = 4x . . . . . . . subtract 8x
Since we want to know the value of 12x, we can go directly there
... 18 = 12x . . . . . . multiply the above equation by 3
m∠KIH = 18°
