Answer 2

Answer:

If the radius is= 2 centimeters, then the circumference of a circle is 12.46 cm and the area of the circle is 12.46 sq. cm.

Step-by-step explanation:

Given: radius (r) = 2 centimeters

Find the circumference and the area of the circle.

Formula: The circumference = 2π  r

and the area of the circle  $=\pi r^2$

Step 1: Find the circumference of a circle

$=2\pi r\\= 2 \times 3.14 \times 2\\= 4 \times 3.14\\= 12.56cm$

So,  the circumference of a circle is 50.24 cm

Step 2: Find the area of the circle

$=\pi r^2\\=3.14 \times (2)^2\\= 3.14 \times 4\\=12.46 sq. cm$

So, the area of the circle is 12.46 sq. cm
