Question

An infant playpen is in the shape of a circle. If the playpen has a diameter of 2 meters, what is the approximate area of the playpen? (Use 3.14 as an approximation of pi.)

Answer 1

The approximate area of the playpen is 3.14 square meters.

Step-by-step explanation:

The area of a circle can be found using the formula A = πr², where A is the area and r is the radius. In this case, the playpen has a diameter of 2 meters, so the radius is half of the diameter, or 1 meter. Using the approximation of pi as 3.14, we can calculate the approximate area of the playpen:

A = 3.14 × (1 meter)² = 3.14 square meters

Therefore, the approximate area of the playpen is 3.14 square meters.
