Question

if a circle has a perimeter of 44cm,then find its diameter.​

Answer 1

Step-by-step explanation:

p=2πr

44=2×22/7×r

r=44×7/2×22

r=7

d=7×2=14

Answer 2

Answer:

diameter = 14 cm

Step-by-step explanation:

the perimeter is given as 44 cm

we know perimeter of a circle is 2πr

⇒ 2πr = 44

⇒ (2)(22/7)(r) = 44

⇒ r = (44)(7)/(2)(22)

⇒ r = 7

we know diameter = 2( radius )

                               = 2(7)

therefore diameter= 14 cm
