Answer 1

The radius of the circle is half of the diameter, so the radius is 14 centimeters.
To find the area of a circle, we use the formula A = πr^2.
Substituting in the values, we get:
A = 3.14 x 14^2
A = 3.14 x 196
A ≈ 615.44 (rounded to two decimal places)

The estimated area of the circle is 615.44 square centimeters.
