Question

What is the area of point O?

Answer 1

A = 28.27

Explanation:

A = π r^2

A = π 3^2

A= π (9)

A = 28.27433

Answer 2

28.26 cm²

Explanation:

It's not the point O, but the circle O.

The area of a circle is given by the formula A = π r²

We already have r (3cm)... so we can plug it directly into the equation:

A = π r² = π 3² = 9π = 28.26 cm²
