Question

Can anyone help me please?

Answer 1

12 in²

Explanation:

to understand the solving steps

you need to know about:

• 
  `circle`
• 
  `area \: of \: a \: circle \: = \pi r ^(2)`
• 
  `pemdas`
• 
  `redious \: of \: a \: circle \: = (d)/(2)`

given:

diameter:4in

π≈3

to solve:

redious

area of the circle

let's solve:

to figure out the area

we need to figure out the redious first

so the redious is 4/2 =2in

and the area of the circle is

πr²

3×2² in²

3×4 in²

12 in²

Answer 2

12inches because 3 is pi and 2 is Radius so 3x2squared=12
