Answer:
1. Area of a circle = 452.2 m²
2. Area of a circle = 1,017.4 ft²
Step-by-step 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
