28.	a circular Garden has radius 56 metre a 7 metre Wide Road runs outside around it find the area of the road what will it cost to gravel the road at rupees 50 per square metre
Answer» Answer: Area of ROAD is 2616.95 $<klux>METRE</klux>^{2}$ . Cost to gravel the road is 130847.50 rupees. Step-by-step explanation: RADIUS of the Garden is R = 56 metre So, area of the Garden is $\pi R^{2}$ = $\pi 56^{2}$ $metre^{2}$ Radius of the (Garden+Road) is (R+7) = (56 + 7) metre = 63 metre So, area of the (Garden+Road) is $\pi (R+7)^{2}$ = $\pi 63^{2}$ $metre^{2}$ Now, (Area of Road) = (Area of Garden+Road) - (Area of Garden) So, area of Road is ( $\pi 63^{2}$ - $\pi 56^{2}$ ) $metre^{2}$ = 2616.95 $metre^{2}$ Cost to gravel the Road is rupees 50 PER $metre^{2}$ . So the TOTAL cost to gravel the road is (Area of the Road)(Cost per $metre^{2}$ ) = (2616.95 50) rupees = 130847.50 rupees.

28.

a circular Garden has radius 56 metre a 7 metre Wide Road runs outside around it find the area of the road what will it cost to gravel the road at rupees 50 per square metre

Answer»

Answer:

Area of ROAD is 2616.95 $<klux>METRE</klux>^{2}$ .

Cost to gravel the road is 130847.50 rupees.

Step-by-step explanation:

RADIUS of the Garden is R = 56 metre

So, area of the Garden is $\pi R^{2}$ = $\pi 56^{2}$ $metre^{2}$

Radius of the (Garden+Road) is (R+7) = (56 + 7) metre = 63 metre

So, area of the (Garden+Road) is $\pi (R+7)^{2}$ = $\pi 63^{2}$ $metre^{2}$

Now, (Area of Road) = (Area of Garden+Road) - (Area of Garden)

So, area of Road is

( $\pi 63^{2}$ - $\pi 56^{2}$ ) $metre^{2}$ = 2616.95 $metre^{2}$

Cost to gravel the Road is rupees 50 PER $metre^{2}$ .

So the TOTAL cost to gravel the road is

(Area of the Road)*(Cost per $metre^{2}$ ) = (2616.95 * 50) rupees = 130847.50 rupees.
