Question

PLEASE HELP

Find the Area

2cm

___cm^2

Answer 1

3.14 cm^2

Explanation:

A=
`\pi`r^2

r=2

2/2=1

A=
`\pi`(1)^2

=
`\pi`1

≈3.14x1

≈3.14cm^2

Answer 2

3.14 cm^2

Explanation:

1. Find radius:

If diameter is 2, divide it by 2 to get radius = 1

2. Find formula:

A=πr^2

3. Plug in:

A = π(1)^2

4. Solve (multiply):

A = π(1)^2:

3.14159265359

Or

3.14 cm^2
