Question

A 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.)

a. 3.14 square meters
b. 3.1416 square meters
c. 3.1428 square meters
d. 3.142 square meters

Answer 1

The approximate area of the playpen is a. 3.14 square meters.

Step-by-step explanation:

The formula to find the area of a circle is A = πr², where A represents the area and r represents the radius of the circle.

In this case, the playpen has a diameter of 2 meters, so the radius would be half of that, which is 1 meter.

Substituting the value of the radius into the formula, we get A = π(1m)² = π(1m)(1m) = π(1m²) = π square meters.

Using the approximation of π as 3.14, the approximate area of the playpen would be 3.14 square meters.
