the area of the circle is 460 cm²

Step-by-step explanation:

circumference of a circle = 2πr

r = radius

let π = 3.14

circumference of the circle = 76cm

76 = 2 × 3.14 × r

76 = 6.28× r

76 = 6.28r

76/6.28 = 6.28r/6.28

r = radius = 12.1cm

Diameter = 2 × 12.1cm = 24.2cm

Area of a circle = πr²

Area = 3.14 × (12.1)²

Area = 459.7 cm²

Approximately to the nearest whole number, the area of the circle is 460 cm²
