Question

find the circumference of circle whose radius is 8.4 cm​

Answer 1

Answer:

52.752 cm

Step-by-step explanation:

circumference of circle= 2$\pi$r

given:- radius of the circle= 8.4 cm.

2*$\pi$*r

2*3.14*8.4

52.752

Thus, the answer is 52.752 cm

Answer 2

Given :-

• Shape = Circle
• Radius of Circle = 8.4cm

To Find :-

• Circumference of the Circle

Solution :-

❏ As we know that, Circumference of a Circle is given by 2πr .

Putting the Values :

➞ Circumference of Circle = 2πr

➞ Circumference of Circle = 2 × 22/7 × 8.4

➞ Circumference of Circle = 44 × 8.4 / 7

➞ Circumference of Circle = 369.6 / 7

➞ Circumference of Circle = 52.8cm

Thus Circumference of Circle is 52.8cm
