alleryFinding the area of a circle here uses which curves in standard form?
AA linear equation
BA random equation
CIts own equation
DA cubic equation
Answer & Solution
Correct answer: C. Its own equation
1. The worked example starts from x squared plus y squared.
2. That is the standard equation of a circle.
3. The integral is set up directly from it.
4. So the answer is its own equation.
