If a circle has radius 5, what is its area?

Explanation:
The area of a circle is π times the radius squared. With a radius of 5, that becomes π × 5^2 = π × 25 = 25π. This is the correct result because it uses the standard formula and the given radius properly. The other numbers come from misapplying the formula: using πr would give 5π, not πr^2; using πr^3 or doubling the area would yield 125π or 50π, which aren’t correct for area.
