Question

choose the correct option. If diameter of circle 14 cm then circum ference is _______ (1) 22cm (2) 42cm (3) 35cm​

Answer 1

Answer :

• Circumference is 44cm

Given :

• Diameter of circle is 14cm

To find :

• Circumference

Solution :

Given , Diameter is 14cm

First we need to find the radius

As we know that,

• Radius = Diameter/2

》Radius = 14/2

》Radius = 7cm

Hence , Radius is 7cm

Now, we have to find the circumference:

As we know that

• Circumference of circle = 2πr

Where , r is radius

》Circumference of circle = 2πr

》2 × 22/7 × 7

》2 × 22

》44cm

Hence , Circumference is 44cm

Answer 2

Answer:

(2) 42 cm

Step-by-step explanation:

Diameter of circle is d = 14 cm

radius of circle is r = d/2 = 14/2 cm = 7 cm

Circumference of the circle is = 2 × π × r = 2 × π × 7  cm = 43.98 cm

so the nearest value from the given options is 42 cm

The answer is (2).
