Question

a circle is inscribed in a square of side 28 cm. Find the area of the circle solve this problems

Answer 1

Answer:

area =7/11

Step-by-step explanation:

given:

side of square=28

therefore circumference of a circle =side of square

=28

now,

circumference=2 pie *r2

28=2*22/7*r2

28*7=44*r2

196=44*r2

root 196=44*r

14=44*r

14/44=r

7/22=r

now,

the value of r=7/22

therefore

area of a circle=pie *r2

=22/7*(7/22)2

=22/7*49/44

=7/11

i.e area =7/11

Hope it helps u!!

thank u!!
