Answer 1

Answer:

Given:

circumference of the circle=2.2 m

πd=2.2 m

22/7×d=2.2

d=22/10×7/22

=154/220

=0.7

Answer 2

Answer:

given, circumference of drum = 2.2m

to find, diameter of drum

soln- let the value of pie be 22/7

circumference = pie d

220cm= 22/7*d

d= 220*7/22

d= 10*7

d= 70cm=0.7m
