Question

Solve it plzz <br />the diametre of a circular park is 24m. A 3m wide path runs around it from inside. find the cost of paving the path at ruppes 25 sq.m​

Answer 1

Answer:

D=24m

r=d/2

=24/2

=12m

Width of the path=3m

Radius of circle including path=12+3

=15m

Area of

path=area of circle including the path-area of park

=πr^2-πr^2

=π(r^2-R^2)

=π(15^2-12^2)

=π(225-144)

=π(81)

=3.14(81)

=254.34m^2

Area of path=254.34

Cost of paving=area ×cost per m^2.

=254.34×25

=5595.48Rs
