Answered by 1muskansahu

hello friend here is your answer....
hope it helps...
according to the question...
radius of circle=49cm
Therefore, circumference of circle=2πr
=2×3.14×49
=307.72 cm.
so, perimeter of square will be equal to the circumference of the circle....
perimeter of square=307.72 cm
4×side=307.72
side=307.72/4
side=76.93 cm.

answer:76.93 cm
if it helps mark as brainliest....
thankyou

1muskansahu: hello ....

1muskansahu: actually my answer is little bit wrong because i had put the value of π to be 3.14 that is not exact value of it.....so instead of this if we put 22/7 the answer will be more appropriate .......

1muskansahu: by the 76.93 is nearly to 77.....

mills: actual value of π is 22/7

mills: what i checked that 49 being divisible by 7 so value of π can be taken as 22/7 to get exact answer

1muskansahu: ya you are right

mills: ur in which standard

1muskansahu: 9th.....you???

This is the Answer;'"

So

$circumference = 2\pi \: r \\ \\ = 2 \times \frac{22}{7} \times 49 \\ \\ = 2 \times 22 \times 7 \\ \\ = 308cm \\ \\ perimeter \: of \: the \: square \: = 308 \\ \\ the \: sides \: of \: the \: square = \frac{308}{4} \\ \\ the \: sides \: of \: a \: square \: = 77cm \\ \\ the \: answer \: is \\ 77cm \: is \\ \\\: the \: sides \: of \: the \: square$

hope it helps
