To find the area of the base of the jar, we need to use the formula for the area of a circle, which is A = πr^2. Since the diameter is given, we first need to find the radius.
Given:
Diameter = 2.75 in
Radius = Diameter / 2 = 2.75 / 2 = 1.375 in
Now, we can calculate the area of the base:
A = π(1.375)^2
A = 3.14159 * 1.890625
A = 5.9464
Therefore, the area of the base of the jar is approximately 5.95 square inches.
The closest option provided is:
