Question

Julia cuts her round birthday cake into 12 equal slices. She serves 7 of the slices. What is the angle measure of the remaining portion of the cake.

Answer 1

do 5 x 30= 150 therefor 150 is your answer 

Answer 2

Hi there!

Assuming all are equal slices, we know that each slice would contain 30 degrees. Knowing this, 7 of the slices were served, so 5 are left. By multiplying 5 x 30, we can figure out the angle measure of the remaining portion of the cake. Doing this leaves us with 150 degrees left.

Hope this helps!! :)
