Question

The Radius of a circle is 1 m. Find the circumference to the nearest tenth.

Answer 1

Answer:

6.3 m

Step-by-step explanation:

Formula to find circumference of a circle is :

C = 2 π r

So, let us solve now.

C = 2 π r

C = 2 × π × 1

C = 2 × 3.14 × 1

C = 6 . 28

The question is asked for nearest 10 th .

Therefore ,

C ≈ 6.3 m

Answer 2

Answer:

$\boxed{ \rm \: Henceforth, the \: circumference \: to \: the \: “nearest \: tenth " \; would \;be :- }$

$\huge{ \boxed{ \bf \: Circumference \approx \: 6.3 \: m}}$

Step-by-step explanation:

Given:-

Radius = 1 m

To find:-

Circumference to the nearest "tenth".

Solution:-

To find the circumference, we need to solve it using the formula of Circumference.That is ,

$\sf \implies \boxed{ \sf{Circumference} \: \sf = 2\pi{r}}$

Where , r equals to radius.

We know that π equals to,

$\sf \implies\pi = 3.14$

Now,

Put the value of π [3.14] and radius(r) [1] on the formula of Circumference.

$\sf \implies{Circumference} =( 2 \times 3.14 \times 1)m$

Simplify the RHS:

Multiply 3.14 and 2 :-

$\sf \implies{Circumference} = (6.28 \times 1)m$

When a number is multiplied with 1, "1" would have no value.

So,

$\sf \implies{Circumference} = (6.28)m$

Remove the parenthesis:-

$\sf \implies{Circumference} = 6.28 \: m$

Hence, Circumference of the circle equals to 6.28 m.

But,We're asked to find the circumference to the "nearest tenth".

So, the circumference [ 6.28 m] to the nearest Tenth is,

$\sf \implies\boxed{{\sf Circumference} \approx \: 6.30 \: \tt m}$

Which is,

$\sf \implies\boxed{{\sf Circumference} \approx \: 6.3 \: \tt m}$

We are Done!
