Question

the perimeter of a circle is 45 CM more than its diameter then find the perimeter​

Answer 1

Answer:

circle has no perimeter , circumference = 45 more than diameter circumference = 2π , daimeter = 2 radius .

circumference = 45 ×( daimeter )

2× 22/7 ( value of π) = 45 × ( 2r )

44/7 = 90 r

44 /7 ×1/90 = 0.07 radius = .07

circumference = 2×22/7

Answer 2

Answer:

Step-by-step explanation:

Given-

Perimeter of circle=45 times it's diameter

To find - perimeter of circle

Answer = 2πr=45×2r (diameter=2× radius)

44÷7=90r

r = 0.07 units

Perimeter of circle = 2πr

2×22÷7×0.07

=0.44 units
