Answer:

Area of a tire in the drawing = 113.14 cm²

Explanation:

Kiara is drawing a photo of a car using a scale factor of 3.

A scale factor of 3 means that the new lengths will be 3 times the original lengths.

Now, if the radius of each of the car's tires is 2 cm, then the radius of each tire in the drawing will be (2 × 3) = 6 cm.

Therefore, the area of a tire in Kiara's drawing will be = πr² =
(22)/(7) * 6^(2) = 113.14 cm². (Answer)
