144.8 cm
Step-by-step explanation:
Radius = r cm
Circumference = 2πr cm
2πr - r = 528
r ( 2π-1) = 528
r = 528/ (2×22/7 +1)
r = 528/ ( 51/7)
r = 72.4 cm
Diameter = 2r = 144.8 cm

Answer:
Circumference - radius= 528cm
=> 2πr-r=528
=>r(2π-1)=528
=> r=528/2π-1
=> r=528/37/7
=> r=528×7/37
=> r=99.891cm ---(i)
Now,
Diameter=2× radius
=> d=2×99.891{ from(i) }
=> d=199.782cm
Hope it helps!!
