Question

find the area of the largest circle that can be drawn inside the given rectangle of length a cm and breadth b cm (a>b)​

Answer 1

Step-by-step explanation:

length of rectangle = a cm

breadth of rectangle= b cm

area of rectangle = ab cm^2

(as a>b)

then the max circle we can make which has a radius = b/2 cm

Therefore, area of circle= πr^2

then it is = πb^2/4 cm^2

Answer 2

I hope it helps you Plz mark me as Brainliest

Step-by-step explanation:

Area of circle = πr²

in a rectangle length is great than it's breadth [ l > b]

we can only draw a circle inside a rectangle with circle's diameter equal to breadth.

=> d = breadth of rectangle = b

=> 2r = b

=> r = b/2

So, the Area of circle with radius (b/2) is

= πr² = π×(b/2)²

=> b²π/ 4 sq. unit.
