Answer:Therefore, 52.8 m3 of gravel is required to have path to a depth of 20cm.

Answer:here is your answer

Step-by-step explanation:(i) Area of the path =π(R

2

−r

2

)

Here,

R=

2

28

+7=14+7=21 m

r=21−7=14 m

Area of the path =π(21

2

−14

)

=

×245

=770 m

(ii) Area of circular path =π(R

2

−r

2

)

Here,

R=20+2=22

r=22−2=20 m

Area of circular path =π(22
