Question

Identify the area of circle P in terms of pi when the radius (r) is 12 cm.

A. A = 12π cm²
B. A = 72π cm²
C. A = 144π cm²
D. A = 288π cm²

Answer 1

The area of circle P with a radius of 12 cm is approximately 452.39 cm².

Step-by-step explanation:

The area of a circle can be found using the formula A = πr², where π is approximately 3.14159 and r is the radius of the circle.

Given that the radius of circle P is 12 cm, we can substitute the value of r into the formula to find the area:

A = 3.14159 × (12 cm)² = 3.14159 × 144 cm² = 452.38944 cm²

Rounding the result to two significant figures, the area of circle P is approximately 452.39 cm².
