Question

The diameter of a circle is 22cm. find the area of the circle.

Answer 1

380.13.

The area of a circle with a 22 diameter is 380.13. Hope this helps :)

Answer 2

379.94 cm² or 380.13 cm²

Explanation:

Hello!

Given that the diameter is 22 cm, we can find the radius by dividing the diameter by 2.

Radius = 11cm

The formula to find the area of a circle is
`A = \pi r^2`.

• A = area
• π = pi (≈3.14)
• r = radius

We can find the area by plugging in the radius in the equation.

Find the Area

• 
  `A = \pi r^2`
• 
  `A = (3.14)(11)^2`
• 
  `A = (3.14)(121)`
• 
  `A = 379.94`

The area of the circle is 379.94 cm².

If you are using the real value of pi, you would have an answer of 380.13.
