Question

A circular park of 20 m diameter has a circular path of width 1 m just inside the

boundary. Find the area of the path.​

Answer 1

Answer:

The answer is 19 Pi

Step-by-step explanation:

Diameter of larger circle is 20, so radius is 10

Area of bigger circle is pi 102 = 100 pi

diameter of smaller circle is 18

so it's radius is 9.

Area is pi 92 = 81 pi

You find the difference and you get the answer 19 pi.

Answer 2

Step-by-step explanation:

According to question, area of circular path

Area =

π (R² - r²)

Where R = Outer area and r = Inner area

π(10²-9²) = 19π m²
