Question

Find circumference of circle when:
Pi is 22/7 and radius is 2.1

Answer 1

Hey mate..

✌☺

▶Here,
➡π = 22/7
➡r = 2.1 cm

▶And,

➡Circumference = 2 π r

▶So, 2 * 22/7 *2.1

➡= 2 * 22 *0.3

➡= 44 * 0.3

➡= 13.2cm

I hope you get it..

Thanks..

Answer 2

pie is 22/7

radius is 2.1

we know circumference is

$2\pi \: r$

the according to this formula

2*22/7*2.1=13.2

therefore the circumference is 13.2
