Jay is decorating a cake for a friend's birthday. They want to put gumdrops around the edge of the cake which has a 12 in diameter. Each gumdrop has a diameter of 1.25 in. To the nearest gumdrop, how many will they need?

Respuesta :

Answer:

The nearest gumdrop required will be 30.

Step-by-step explanation:

We will find the circumference of the cake which has 12 inches diameter

Radius = diameter / 2 = 12 / 2 = 6 inches

C = 2 x 3.14 x radius

C = 2 x 3.14 x 6 = 37.68 inches

The gum drop dia = 1.25 inches

The total gum drops required to cover 37.68 inches = 37.68 / 1.25 = 30.144

The nearest gumdrop required will be 30.
