Question

Hii !!! solve it
(Please draw the diagram also )-

Circular road of uniform width 7 m runs outside a circular plot of land having diameter 98 m. Calculate calculate the area of the road.

Answer 1

Answer:

2310 m²

Step-by-step explanation:

Given,Diameter of inner circle d = 98 m.

Given, Radius of inner circle r = d/2 = 49 m.

Given, Width = 7 m.

Radius of outer circle R = 49 + 7

                                       = 56 m.

Area of the road = πR² - πr²

                           = π[R² - r²]

                           = (22/7)[56² - 49²]

                           = 22/7[735]

                           = 16170/7

                           = 2310 m².

Therefore, Area of the road = 2310 m².

Hope it helps!
