2+2+9+0+8+1+2+3+4+5+6+7+8+9 is 66
Answer:
Step-by-step explanation:
The formula for arc length is:
Where Θ is measured in degrees.
We know that the arc length is 8π when the degree is 80. So, substitute 8π for A and 80 for Θ:
Divide both sides by 2π:
Simplify the fraction:
Multiply both sides by 9/2:
So, the radius is 18.
Now, we can find the area of the circle. The formula for the area of a circle is:
Substitute 18 into r:
Simplify:
And we're done!
