Question

what is the perimeter of circle with radius 7 cm ... plzzz step by step answer​

Answer 1

Answer:

Formula of perimeter of circle is 2pai r

Here radius(r) =7

Put the value of r in formula

Then

2.22/7.7

=44

Answer 2

Answer:

perimeter of circle = 44cm or 43.68

Step-by-step explanation:

perimeter of circle= 2πr

r = 7 cm

If we take value of π = 22/7

then,

perimeter = 2×22/7×7

= 2×22

= 44 cm

If we take value of π = 3.14

then,

perimeter = 2×3.14×7

= 6.24 × 7

= 43.68 cm
