Question

area of recatngle and the area of the circle is equal . If the length and breadth of the rectangle are 14cm and 11cm respectively . then find the radius of the circle​

Answer 1

Answer:

7

Step-by-step explanation:

lb=pie rsquare

14*11=22/7*r*r

154=22/7*r*r

154*7=22*r*r

1078/22=r*r

49=r*r*

7*7= r*r

therefore the radius of the circle is 7

Answer 2

Step-by-step explanation:

Area of rectangle =Area of circle

Now,

length of rectangle =14cm

breadth of rectangle =11cm

Area of rectangle =length × breadth

==> 14 ×11

==> 154 cm²

Now,

Area of circle = 154 cm²

==> πr² = 154 cm²

==> 22/7 × r² = 154

==>22 r² = 154×7

==> 22 r² = 1078

==> r² = 1078/22

==> r²= 49

==> r =√49

==>r =7

Hence,radius of circle =7
