First and last ones
The " = [number] " at the end of an equation for a circle is the radius squared
So if the diameter is 12, then the radius is 6, and 36 is 6 squared
Also as long as the x term doesn't have an integer affecting it (like -3 or +5) then it'll stay on the y axis.

How to find the area of 2 half circles and a rectangle
gladu [14]
Hello!

We use different formulas to calculate the areas of different shape.

RECTANGLE:

To find the area of a rectangle, we must simply multiply its length by its width. The formula for its area is:

A = l × w

SEMICIRCLE:

Since the formula for a circle is pi × r × r, we must use the same formula but divide it in half, because a semicircle is a half circle, which is why its area would also be half of a circle's. The formula for a semicircle's area is:

A = 1/2 pi × r × r

Tip:

Write these formulas down and memorize them so that you don't forget them. You'll have to use these formulas quite often when finding the area of these shapes.
