The area of a circle is expressed as:
Area = πr²
where r is the radius of the circle. This equation is used to calculate the area of the circle above. Calculation is as follows:
A = π(3.1 x 10^4 cm)² = 3.0 x 10^9 cm²
Answer:
Step-by-step explanation:
Due to the '+1', the graoph of x^2 is shifted 1 unit to the left. The '+9' results in the entire graph being shifted downward 9 units.
