Question

Find the perimeter of a circle with radius 3.5 cm​

Answer 1

Answer:

Given radius of circle is r=3.5 cm

as we know that

Perimeter of circle with radius r is 2πr and area of circle is πr

2

So perimeter of circle is 2π(3.5)=

7

22

×7=22 cm

Area of circle is π(3.5)

2

=

7×4

22×7×7

=38.5 cm

Step-by-step explanation:

this is so easy OK understand

Answer 2

Answer:

$perimeter \: of \: a \: circle = 2\pi \: r$

=2*22/7*3.5

=22cm
