Question

(Q1) Find the circumference of a circul whose radius
i) 14 cm​

Answer 1

Answer:

87.92 cm or round of 88 cm

Step-by-step explanation:

equation of finding circumference of a circle is 2πr

circumference means perimeter of the circle

or the ring or rim or border of the circle

so π = 3.15

r = 14cm

2 x 3.15 x 14 = 87.92 cm ;88cm

Answer 2

Answer:

Question :

To Find circumference of a circle whose radius 14 cm.

To Find :

Circumference ( Perimeter ) of Circle

Circumference Of a circle is called perimeter.

Formula TO Find :

Circumference Of Circle = 2πr

Where ,

• r = radius ( 14 )

• value of π = 3.14

Solution :

Circumference = 2πr

⟶ 2πr

⟶ 2 × π × r

⟶ 2 × π × 14

⟶ 2 × 3.14 × 14

⟶ 6.28 × 14

⟶ 87.92 ( 88 )

Circumference Of Circle = 88 cm

Perimeter Formulas :

• square = 4 × side ( 4a )

a - side of Square

• rectangle = 2 × ( l + b )

l - length, b - Breadth

• triangle = a + b + c

a, b, c - sides of Triangle

• circle = 2πr

r - radius
