given:-circumference of circle=56cm circumference of circle = 2×22/7×R

= 56 = 2×22/7×R

= (56×7)/2×22 = R

=(14×7)/11=R

=98/11=R

R=98/11cm

D=2R

D=2×98/11

D=196/11cm

Answer 2

hi mate,

solution:

5) d= C/π = 56/3.14 = 17.8343949

6) d= C/π = 25.12/3.14 = 8

r = d/2 = 8/2 = 4

i hope it helps you.
