Question

1. If numerical value of the circumference and the area of the given circle are equal, then what is the diameter
2. The perimeter of a square and a circle are equal. If area of the circle is 3850 m, then what will be the area of
the square?
w circles are 4:9, then what is the ratio of their circumference?​

Answer 1

Answer:

Step-by-step explanation:

Given perimeter of square and a circle equal

Area of circle 3850m

Area=pi×r×r

3850m=22/7×r^2

r=35m

Perimeter of circle =2×22/7×35

Perimeter of circle =220m

Given that Perimeter of square =p of circle

Perimeter of square =4×side

220m =4×s

S=55m

Area of square =side ×side

Area = 55× 55 answer
