Question

A spherical glass paperweight has a radius of 1.5 decimeters. The glassblower wants to know the surface area in square centimeters to estimate the amount of paint needed for decoration. What is the surface area of the paperweight in square centimeters? (Use π ≈ 3.14, 1 decimeter = 10 centimeters)

Question Analysis
This question involves converting the unit of the radius from decimeters to centimeters and then calculating the surface area of the sphere.
The main focus is on correctly using the unit - conversion factor and applying the surface - area formula.

Key Concept Explanation
Convert the radius from decimeters to centimeters using the given conversion factor.
Then substitute the converted radius into the formula to find the surface area in square centimeters.

Step - by - Step Solution
Convert the radius from decimeters to centimeters: decimeters = 1.5 x 10 = 15 centimeters.
Calculate the surface area: ,
