Question

plss help me to solve this

Answer 1

Heya...
Here is your answer ---

=> Circumference of park = 55m

=> Radius = Circumference / (2 × π)
= 55 / (2 × 22/7)
= 55 / (44/7)
= 55 ÷ 44/7
= 55 × 7 /44
= 5 × 7/4
= 35/4
= 8.75 m

=> Area of park = π × r^2
= 22/7 × (8.75)^2
= 22/7 × 76.56
= 22 × 9.93
= 239.8 m^2

=> Radius of the park along with path = 8.75 + 3.5
= 12.25

=> Area of park along with path = π × r^2
= 22/7 × (12.25)^2
= 22/7 × 150.0625
= 22 × 21.44 (approx)
= 470.8 m^2

=> Area of path = 470.8 - 239.8
= 231

HOPE IT HELPS...!!!
