Answer:

Area = 30.18 cm^2

Explanation:

Formula for the area of a circle:

The formula for the area of a circle is given by:

A = πr^2, where

  • A is the area in units squared,
  • and r is the radius.

Thus, we can find the circle's area (A) to the nearest hundredth by substituting 3.14 for π and 3.1 for r in the circle area formula:

A = 3.14(3.1)^2

A = 3.14(9.61)

A = 30.1754

A = 30.18

Thus, the area is about 30.18 cm^2.
