Mrs. Smith made a cake that has a diameter of 7 inches and a height of 5.5 inches, as shown below. She wants to design a new cake by dilating the dimensions of the original cake by a scale factor of 1.4

What will be the diameter of the new cake?

The diameter of the new cake will be 9.8 inches.

Step-by-step explanation:

Mrs. Smith's cake has a diameter of 7 inches and a height of 5.5 inches.

Now, she wants to design a new cake by dilating the dimensions of the original cake by a scale factor of 1.4.

Therefore, each dimension of the old cake will be multiplied by factor 1.4.

Therefore, the diameter of the new cake will be (7 * 1.4) = 9.8 inches. (Answer)
