The shaded area will be given by:
A=(area of the outer circle)-(area of the inner circle)
area of outer circle:
A=πr²
A=π(2x)²=4x²π
Area of the inner circle:
A=π×6²=36π
Thus the shaded area will be:
4x²π-36π=364π
4x²π=400π
4x²=400
x²=100
x=√100
x=10 cm
Value if x is 10 cm
Answer is; 7/3, which is 2 and 1/3 or you can say 2,333.....
Why?
63/27=7*9/3*9 ; {removing 9 from both gives 7/3}
Answer:
Explanations:
To convert angles from degrees to radians, multiply the angle by π/180
For angle 126°, the equivalent measurement in radian is:

Reduce to the lowest term by dividing the numerator and denominator by 18:
