For a round pool, a 1-meter-wide path should be paved around it. How many square meters is the area of the path?

For a round pool, a 1-meter-wide path should be paved around it. How many square meters is the area of the path?

Radius of inner circle: 4 △ 2 = 2 (m), area of path: 3.14 × (1 + 2) 2-3.14 × 22 = 3.14 × (32-22) = 3.14 × 5 = 15.7 (M2); answer: area of path is 15.7 m2

There is a round pool with a diameter of 4 meters. A 1 meter wide path should be paved around it. How many square meters is the area of the path?

Hanying warm for you
4 △ 2 = 2m
2 + 1 = 3M
3.4×3×3-3.14×2×2
=15.7 square meters
The area of the path is 15.7 square meters

A round pool is 4 meters in diameter, and a 1-meter path is paved around him. What is the area of the path?

The area of the path is equal to a circle of 6 meters in diameter minus a circle of 4 meters in diameter
3.14 * 3 * 3-3.14 * 2 * 2 = 3.14 * 5 = 15.7m2
