What is the area of the shaded region?

Given:

Radius of in circle (r) = 2 cm

Radius of out circle (R) = 4 cm

To find:

The area of the shaded region.

Solution:

The value of π = 3.14

Area of in circle = πr²

                          = 3.14 × 2²

Area of in circle = 12.56 cm²

Area of out circle = πR²

                          = 3.14 × 4²

Area of out circle = 50.24 cm²

Area of the shaded region = Area of out circle - Area of in circle

                                            = 50.24 - 12.56

                                            = 37.68 cm²

The area of the shaded region is 37.68 cm².

all you have to do is multiply them both to see how many out comes you can put:

3 x 2 = 6

you can make 6 diferent combinations of crusts and toppings.
