Question

A circular field is 100 m in diameter and surrounded by a 7 m wide circular path. The area of path is
​

Answer 1

let outer radius be R

inner radius be r

R-r = 7m

R = 100/2 = 50m

r = 50-7 = 43m

area = π(R²-r²) = π {(50)²-(43)²}

solve and get the answer bro

Answer 2

Answer:

Let outer radius be R

Inner radius be r

R = 100/2 =50+7 = 57

r = 50

22/7(R^2 - r^2) = 22/7(3249-2500)

22/7 × 749
