Answer:
Where is the equation?
Step-by-step explanation:
The answer is D because that is the closest answerr to 40
Answer:
A = 27π cm² or about 84.8 cm²
Step-by-step explanation:
Area of a full circle is πR²
As there are four right angles making up a 360° turn, and the missing piece is one of those four, there are ¾ of a circle remaing
A = ¾πR² = ¾π6² = 27π cm² or about 84.8 cm²

We're given that
and
, and want to find
.
By the chain rule, we have

and


Then

(because the point
corresponds to
)
