Answer 1

circumference =2×22/7×r
44/7×r=220
r=220×7/44
=35 cm

d=70 cm

radius and diameter are 35 cm and 70 cm

hope it helps

Answer 2

Answer:radius=110/pi & diameter=220/pi

Step-by-step explanation:

As circumference of a circle is 2pi.r

Therfore, 2pi.r=220

. r=220/2pi

. r=110/pi

Again,D=2r

. D=220/pi
