The formula for the area of a circle is the following:

A =   \pi r^{2}

where A is the area and r is the radius of the circle. We also know that the diameter of a circle is twice the length of the radius, so you are able to determine the radius using the above formula, and then you can double it to get the diameter.

MissTica
Times the price of the model cars to the amount bought.

$15×6= 90.

Lea paid 90 dollars for the model cars.

Now, multiply the price of the paint to the amount bought.

$11×4= 44.

Lea paid 44 dollars for the paint.

Add both together. 90+44= 134.

Therefore, Lea paid $134 for the model cars and paint all together.
