Question

a wire when bent to form a square encloses an area of 992.25cm².if the same wire is bent to form a semicircle, what will be the radius of the semicircle so formed??? ​

Answer 1

Answer:

10.02

Step-by-step explanation:

Area of square= side^2

992.25= side^2

31.5= side

perimeter of square= 4 × side

=126

the same wire is bent and formed a semi circle

so,

perimeter of semicircle=perimeter of square

πd=126

d=126/π

d=40.09

therefore r=d/2

r=20.045
