Question

Find the circumference of a circle whose diameter is 35 cm​

Answer 1

Answer:

diameter is 35 cm

Radius= 35/2 cm

Step-by-step explanation:

Circumference= 2×22/7×35/2 cm =110 cm

Answer 2

Given:

• Diameter of circle = 35 cm

To find:

• Circumference of the circle

$\:$

Solution:

We are given the diameter of circle, i.e., 35 cm,

So, radius of circle is $\underline {\sf {\red {\dfrac {35}{2}\ cm}}}$

$\:$

We know that,

$\boxed {\mathfrak {\orange {Circumference\ of\ circle = 2 \pi r}}}$

Where,

• r stands for radius of the circle
• π is a constant, whose value is 3.14 or $\sf \dfrac {22}{7}$

Substitute the values,

Circumference = 2π× $\sf \dfrac {35}{2}$

Circumference = $\sf {2 \times \dfrac {22}{7} \times \dfrac {35}{2}}$

Circumference = $\sf {2 \times \dfrac {\cancel{22}}{\cancel{7}} \times \dfrac {\cancel{35}}{\cancel{2}}}$

Circumference = 2×11×5

$\bigstar {\mathcal {\pink {Circumference = 110\ cm}}}$

$\:$

Circumference:

Circumference of circle whose diameter is 35 cm is 110 cm.
