Find the area of the circle with the following dimension diameter = 4 cm
Elis [28]

Answer:

A = 12.56 cm^{2}

Step-by-step explanation:

<u>When you want to find area out of diameter. These are the steps you follow:</u>

1. Convert diameter to radius

2. Solve for area

<u></u>

<u>First step:</u>

When you need to convert diameter to radius, you just need to divide by 2

d = 4cm / 2cm

==> 2cm

<u>Second step:</u>

Use formula  A = \pi * r^{2}

A = \pi * 2cm^2

A = \pi * 4cm

A= 12.56cm
