Question

AreA of a circle pls help​

Answer 1

28.26

Explanation:

You want to plug everything in to the equation that you can. It says that pi=3.14, and the radius (aka r) is equal to 3. Therefore when plugging everything in, the equation reads (3.14)(3)^. ^ means squared, its the tiny 2 above the r. when something is squared it means you multiply it by itself 2 times. therefore 3 squared = 3 x 3= 9. After finding out 3^=9, the equation reads (3.14)(9). Now all you have to do is multiply the 2 together which results in 28.26.

Answer 2

28.26
`in^(2)`

Explanation:

Given,

Radius of the circle = 3in.

Area = ?

They have told us to use 3.14 for
`\pi`

Area formula =
`\pi r^(2)`

=> 3.14 * 3 * 3

=> 3.14 * 9

=> 28.26
`in^(2)`

Therefore the area of the circle is 28.26
`in^(2)`

Hope it helps :)
