1.	The diameter of a circular park is 56 m. On its outside, there is 3 m wide path, running around it. findcost of turfing the path at 5 per square metre.
Answer» Diameter of CIRCLE=56m. RADIUS of circle= diameter/2. R=56/2. R= 28 Around PATH of 3m. Full radius of circle=28+3=31. Volume of circle=2πr. V.of.circle=2×22/7×31 V.of circle= 1364/7. v.of.circle=194.8m2. with path. V.of circle= 2πr=2×22/7×28 V.of circle=176m. V.of .circle with path- V.of circle. 194.8-176 . =18.8m. Cost if path =18.8×5. Cost of path =94 RUPPEE.

Answer»

Diameter of CIRCLE=56m.

RADIUS of circle= diameter/2.

R=56/2.

R= 28

Around PATH of 3m.

Full radius of circle=28+3=31.

Volume of circle=2πr.

V.of.circle=2×22/7×31

V.of circle= 1364/7.

v.of.circle=194.8m2. with path.

V.of circle= 2πr=2×22/7×28

V.of circle=176m.

V.of .circle with path- V.of circle.

194.8-176 .

=18.8m.

Cost if path =18.8×5.

Cost of path =94 RUPPEE.
