hii!!
here's ur answer...
given that the length of the piece of wire is 352cm and it's bent into a circle.
therefore the circumference of the circle is 352cm.
=> 2πr = 352cm
=> 2×22/7×r = 352cm
=> 44/7×r = 352cm
=> r = 352/1×7/44
=> r = 8×7
=> r = 56cm
VERIFICATION:-
circumference of the circle = 2πr
= 2×22/7×56
= 44×8
= 352cm
hence verified
thus the radius of the circle is 56cm.
we know that diameter is double of radius, there diameter of the circle = 56×2
= 112cm
hope this helps..!

use the formula for circumference of a circle and solve:
22/7 * d = 352cm or 2 * 22/7 * r=352
d or 2r=112cm.
22/7 * d = 352cm or 2 * 22/7 * r=352
d or 2r=112cm.
tnx
no probs
