A sphere with a radius of 1.7 cm has a surface area of: A) 2.1 *10^-⁵ m² B) 9.1 * 10^-⁴ m² C) 3.6 * 10^-³ m² D) 0.11 m² E) 36 m²

Question

Quizplus · Accepted Answer

The formula for the surface area of a sphere is 4πr², where r is the radius of the sphere. Substituting the given radius of 1.7 cm into the formula gives: 4π(1.7 cm)² = 4π(2.89 cm²) = 11.51 cm² Converting cm² to m² gives: 11.51 cm² × (1 m/100 cm)² = 0.001151 m² Rounding to one decimal place gives the final answer of 3.6 F1F1F1S1F1F1F10 10^-³ m². Therefore, the correct answer is C).
