Question

Estimate the area of the circle using 22/7

Answer 1

Answer:
`A_(circle)=616cm^2`

Explanation:

You can observe in the figure that the value of the diameter of the circle is

`d=28cm`

Then, since you know the diameter , you can use this formula for calculate the area of the circle:

`A_(circle)=(\pi d^2)/(4)`

Where "d" is the diameter.

Then, substituting
`d=28cm` and
`\pi =(22)/(7)` into the formula, you can estimate the area of the circle. This is:

`A_(circle)=(((22)/(7))(28cm)^2)/(4)`

`A_(circle)=616cm^2`
