Answer 1

Answer:

radius of the circle is 132×7/2×22

that is...21

then diameter is 21+21

i.e. 42....

hope it help u.. .

Answer 2

given

circumfrence of circle = 132 cm

formula for circumfrence = 2π r

now

2 π r = 132

r = 132 / 2π

r = 132 / 2 ( 22/ 7)

r = 132 .7 / 44

r = 924 / 44

r = 21 cm

as diamter is double of radius

diameter = 21 + 21 = 42 cm
