Question

10. A circular park of radius 15 m has a path of
10 m width around its outer side. Find the
area of the road.
​

Answer 1

Answer:

r=15m

outer radius R=25m

area of road=π(R^2-πr^2)

π(25-15)(25+15)

π(10)(40)

400π

1256sqm

Answer 2

Step-by-step explanation:

radius along with road= 15+10=25

Area of road along park= 22/7×25×25

=13750/7

Area of park=22/7×15×15=4950/7

Area of road =Area along with park-area of park

13750/7-4950/7=8800/7
