Question

Find The circumference of a circle having diameter 10m π3.14

Answer 1

Answer :

• The circumference of a circle is 3.14 m

Given :

• Diameter is 10m

To find :

• The circumference of a circle

Solution :

Given that Diameter is 10m . so firstly we have to find the radius then after we have to find the circumference using the formula of circumference of circle

Given Diameter is 10m

• Radius = D/2 = 10/2 = 5m

Radius is 5m

As we know that :

• Circumference = 2πr

where , π is 3.14 and r is 5m

➵ 2 × 3.14 × 5

➵ 3.14 × 2 × 5

➵ 3.14/100 × 10

➵ 314/10

➵ 31.4 m

Hence Circumference Of circle is 31.4 m

Answer 2

AnswEr-:

• $\underline {\boxed{\dag{\mathrm {\blue{Circumference \:of\:Circle \:-: 31.4 \:m}}}}}$

Explanation-:

• $\mathrm { Given-:}$

• The diameter of Circle-: 10 m

• $\mathrm{ To\:Find-:}$

• The Circumference of Circle.

$\dag{\mathsc{Solution \:of\:Question -:}}$

• $\underbrace {\mathrm { Understanding \:The\:Concept \:-:}}$

• We have to find the Circumference of Circle.

• For this first we have to find the Radius of Circle and by putting Radius of the circle in the Formula for Circumference of Circle. By doing this -:

• We can get the Circumference of Circle.

As , We know that ,

• $\underline {\boxed{\dag{\mathrm {\red{Radius \:of\:Circle \:-: \dfrac{Diameter}{2}}}}}}$

• $\mathrm { Here-:}$
• The diameter of Circle-: 10 m

Now , By Putting known Values-:

• $\longrightarrow {\mathrm { Radius =\dfrac{10}{2}}}$

• $\longrightarrow {\mathrm { Radius =\dfrac{\cancel {10}}{\cancel {2}}}}$

• $\longrightarrow {\mathrm { Radius =5 m}}$

Therefore,

• $\boxed {\mathrm { Radius\:of\:Circle =5 m}}$

As , We know that ,

• $\underline {\boxed{\dag{\mathrm {\red{Circumference \:of\:Circle \:-: 2\times \pi \times Radius}}}}}$

• $\mathrm { Here-:}$

• $\longrightarrow {\mathrm { Radius =5 m}}$

• $\pi=3.14$

Now , By Putting Known Values-:

• $\longrightarrow {\mathrm { Circumference \:= 2 \times 3.14 \times 5}}$

• $\longrightarrow {\mathrm { Circumference \:= 10 \times 3.14 }}$

• $\longrightarrow {\mathrm { Circumference \:= 10 \times 3.14 }}$

• $\longrightarrow {\mathrm { Circumference \:= 31.4 m}}$

Hence ,

• $\underline {\boxed{\dag{\mathrm {\blue{Circumference \:of\:Circle \:-: 31.4 \:m}}}}}$
