Answer:

1. Area of a circle = 452.2 m²

2. Area of a circle = 1,017.4 ft²

Explanation:

Area of a circle = πr²

1.

When radius, r = 12 m

π = 3.14

Area of a circle = πr²

= 3.14 * (12m)²

= 3.14 * 144 m²

= 452.16 m²

Approximately to the nearest tenth,

Area of a circle = 452.2 m²

2.

When radius, r = 18 ft

π = 3.14

Area of a circle = πr²

= 3.14 * (18 ft)²

= 3.14 * 324 ft²

= 1,017.36 ft²

Approximately to the nearest tenth,

Area of a circle = 1,017.4 ft²
