Question

Find the circumference of the circle below

Answer 1

• 62.8 ft

Explanation:

Given

• Diameter = 20
• Radius= ?
• Circumference = ?

To find out

• Circumference

By Using

• Circumference of circle = 2πr

Solution

We know that

• Radius = d/2

So,

→ R = 20/2

→ R = 10

Now,

We know that,

Circumference of circle = 2πr

→ 2 × 22/7 × 10

→ 440/7

→ 62.8 ft

Hence ,

Option d is correct answer

Answer 2

Hello !

Answer:

`\boxed{\sf C\approx62.8 ft}`

Explanation:

To find the circumference of a circle with its radius, we will apply the following formula:

`\sf C=2\pi r`

Where r is the radius of the circle.

Given :

• diameter = 20 ft

We know that the diameter is equal to two times the radius, so
`r=10` ft.

Let's substitute our value into the formula :

`\sf C=2* \pi* 10\\\boxed{\sf C\approx62.8 ft}`

Have a nice day !
