Answer:

1) A = π(14 cm)² = 196π cm²

= about 616 cm²

2) A = π(7.5 ft)² = (15/2)²π ft² = 225π/4 ft²

= about 177 ft²

Answer:

  • circle: 616 cm²
  • target: 1.77 ft²
  • tortilla: 113.10 in²

Explanation:

You want the areas of the circle figures:

  • circle, radius 14 cm
  • target, diameter 1.5 ft
  • tortilla, diameter 12 in

Area

The area of a circle is given by the formulas ...

A = πr² = (π/4)d² . . . . . where r is the radius, d is the diameter = 2r

Circle

The area of the circle of radius 14 cm is ...

A = π(14 cm)² ≈ 616 cm²

Target

The area of the target with diameter 1.5 ft is ...

A = (π/4)(1.5 ft)² ≈ 1.77 ft²

Tortilla

The area of a 12-inch tortilla is ...

A = (π/4)(12 in)² ≈ 113.10 in²
