Question

Palash and Piyali have drawn two circles the ratio of which length of radius is 4:5. Letus write by calculating the ratio of the area of two circular fields drawn by them​

Answer 1

Answer:

Area of circle = pie r sq.

.

Therefore area of the two will be = 4×4×22/7 ÷ 5×5×22/7

.

So pie gets cut.

.

Ans = 4×4/5×5 = 16/25

Answer 2
