What is the circumstances
Please help me and thnx u if u help me on this

Answer 1

35.19

Explanation:

equation is : C=2πr

Answer 2

`\Large \underline{\tt Given} :`

• Diameter of circle, d = 5.6 cm

`\\`

`\Large \underline{\tt To \: Find} :`

• Circumference = ?

`\\`

`\Large \underline{\tt Solution} :`

As, we have diameter of circle is 5.6 cm and radius is half of diameter.

`\tt : \implies Radius, r = (d)/(2)`

`\tt : \implies Radius, r = (5.6 \: cm)/(2)`

`\tt : \implies Radius, r = \frac{\cancel{56} \: cm}{10* \cancel{2}}`

`\tt : \implies Radius, r = (28 \: cm)/(10)`

`\tt : \implies Radius, r = 2.8 \: cm`

`\\`

Now, for Circumference :

`\Large \underline{\boxed{\bf{Circumference = 2\pi r}}}`

`\tt : \implies Circumference = 2 * (22)/(7) * 2.8 \: cm`

`\tt : \implies Circumference = \frac{44}{\cancel{7}} * \frac{\cancel{28}}{10} \: cm`

`\tt : \implies Circumference = 44 * (4)/(10) \: cm`

`\tt : \implies Circumference = (176)/(10)\: cm`

`\tt : \implies Circumference = 17.6\: cm`

`\\`

Hence, circumference is 17.6 cm.
