Question

find the circumference of the circle whose diameter is 1) 84 CM ​

Answer 1

Circumference of the circle = 2πR

where π = 22/7 and

R = radius of the circle

Diameter = radius×2 = 84 cm {given}

Radius = diameter/2 = 84/2 = 42 cm

Circumference of the circle = 2×(22/7)×42

= 2×22×6

= 44×6

= 264 cm

Answer 2

Given :

⬤ Diameter is 84 cm .

To Find :

⬤ Circumference of Circle .

Formula Used :

$\bf[\:{Circumference\:of\:Circle=2\pi{r}}\:]$

• r = radius

Solution :

• Diameter = 84 cm .
• Radius = 42 cm.

Now :

According to the Formula :-

2πr

2 × 22/7 × 42

2 × 22 × 6

264

Therefore , The Circumference of the Circle is 264 cm .
