Question

What is the approximate area of the circle shown?

Use 3.14 to approximate pi. Round your answer to the nearest whole number.

Circle diameter is 18

Answer 1

The area of the circle is 254 square unit. ( approx )

Explanation:

Given,

The diameter of circle = 18 unit,

⇒ The radius of the circle =
`(18)/(2)` = 9 unit,

Since, the area of a circle,

`A=\pi r^2`

Where r is the radius of the circle,

Thus, the area of the circle is,

`A=\pi (9)^2`

`=3.14* 81` (
`\pi` = 3.14 )

`=254.34\text{ square unit}\approx 254\text{ square unit}`
