Answer:
2121 Rounded to the nearest inch.
Step-by-step explanation:
A = Is the formula for a circle, but we only have a portion of a circle so we will have to adjust the formula for a part of the circle.
A =
The
is the part of the circle and the whole circle is 2
is the same as
÷
Which is the same as
x
Which is the same a
A =
A = (3.14)(90)(90) = 2119.5. When you use the
on your calculator you get a slightly different number. This is due to rounding.
A = 2120.575041
We have been given a chord and tangent to a circle. We have been minor arc measure that is equal to .
Since we know that angle formed by a secant and tangent of circle is half of the measure of intercepted arc.
We can find intercepted arc by subtracting minor arc measure from 360 degrees because minor and major arcs add up to 360 degrees.
Now we will plug given values in our formula,
Therefore, the measure of d is 121 degrees.
