Question

5. If area of a square is 44 sq cm then find the
area of circle formed by the same perimeter?
(a) 66 sq cm (b) 55 sq cm
(C) 56 sq cm (d) 50 sq cm
(e) None of these​

Answer 1

Answer:

None of these

Answer 2

Answer:

(C) 56sq cm.

Area of square = 44

Side is square = 2 root 11

Hence, perimeter of square = 4a = 8 root 11

ATQ,

perimeter of square = circumference of circle

2 × 22/7 × r

=> 2 x 22/7 x r = 8 root 11

=> r = 14 / root 11

Area of circle = 22/7 x r^2

= 22/7 x (14/root 11)^2

= 56 cm sq.

Hope this helped you!!
