Question

Judy is baking a round cake for her niece's birthday and the recipe requires her to coat the bottom of the pan with flour. If the cake pan has an 8-inch diameter, what is the area that she will need to cover with flour on the bottom of the pan?

Answer 1

A = 50.24

Step-by-step explanation:

Diameter = 8

8/2 = 4

4 is the radius

A = πr2

A = 3.14 x 42

4 x 4 = 16

A = 3.14 x 16

A = 50.24

Answer 2

A = 50.24

Explanation:

Diameter = 8

8/2 = 4

4 is the radius

A = πr2

A = 3.14 x 42

4 x 4 = 16

A = 3.14 x 16

A = 50.24
