radius = 1/2 diameter = 1/2 * 11 = 5.5 ins

area = pi * r^2 = 3.14 * 5.5^2 = 94.99 in^2 to nearest hundredth

To find the area of a circle you do pi (3.14) multiplied by the radius squared.

The radius is half of the diameter: 11 / 2 = 5.5in

The radius squared is 5.5^2 = 30.25

Then take the squared radius and multiply that by pi 30.25 * 3.14 = 94.985

So the area of the circle is about 94. 99 in.

How do you figure out the area of a triangle?

andrew11 [14]

General formula for area of triangle is $A=\frac{h_bb}{2}$ .

Where:

$h_b$ is height of triangle perpendicular to base side of triangle.
$b$ is the length of base side of triangle.

Multiplying $h_b$ and $b$ results in rectangle, dividing that by 2 gives you area of a triangle.

Hope this helps.
