Question

A circular flowerbed of diameter 66 m is surrounded by a path 4 m wide. Find the
cost of concreting the path at 3 275 per m^2.

(Take π = 3 whole 1/7)​

Answer 1

Step-by-step explanation:

radius of the park with out path 42/2 =21

radius of the park with Path 21 + 3.5 =24.5

area of the park equal to 22/7 ( 24.5 ) *2 -21 square )=500.5

cost =4*500.5=2002

Answer 2

Answer:

Radius of the park without path=42/2=21

Radius of the park with path=21+3.5=24.5

Area of the park=22/7 (24.5)×2-21 square=500.5

Cost=4×500.5=2002
