Question

What is the area of a circle with a diameter of 18.2 cm?

use 3.14 for TT and round your final answer to the nearest hundredth.

the area is ___ square cm.​

Answer 1

260.0234 cm

Explanation:

The formula for area of a circle is π r².

Since the radius is half of the diameter, we must divide the diameter by 2.

18.2/2 = 9.1

Next, we must multiply 9.1 x 9.1.

This gives us 82.81

Now we must multiply 82.81 by pi (3.14).

82.81 x 3.14 = 260.0234

Therefore, the area of the circle is 260.0234.
