Question

What is the difference in area between a circle with a diameter of 3 meters and a square with a side length of 3 meters? Use 3.14 for pie.

pls help me​

Answer 1

the difference in area between a circle with a diameter of 3 meters and a square with a side length of 3 meters=d²-π/4d²

=3²-3.14/4×3²=1.935m²

Answer 2

The area of a circle with a diameter of 3 meters:

• A = πr² = π(d/2)² = 3.14(3/2)² = 7.065 m²

The area of a square with a side length of 3 meters:

• A = a² = 3² = 9 m²

The difference:

• 9 - 7.065 = 1.935 m²

The square has greater area by 1.935 m²
