Which is greater, the area of a red plate that has a radius of 6 cm, or the area of two yellow plates with a radius of 3 cm each?

The area of a red plate with radius 6cm is greater.

Step-by-step explanation:

The general formula for the area of a circle is:

A = πr², where 'r' represents the radius

To compare the areas of the plates, we can set up two different equations:

Red plate: A = π6² or 36π

Yellow plate: A = π3² or 9π

But, there are two yellow plates:

9π + 9π = 18π

36π > 18π, so the area of the red plate is greater.

The red plate has an area larger than that of the two yellow plates.

Step-by-step explanation:

the red plate has the biggest area of all
