Dana is creating an art project. She is drawing circles within circles. Each circle that she draws is .8 the size of the previous circle. If her initial circle had a diameter of 60 cm. How large is the diameter of the 3rd circle she draws?

The question is kind of confusing. if it's asking how many variations of answers can you give. then do 4^5 for your answer.this would be something like the first question could be a and the 2nd c or first b next c etc. if you can, ask the teacher for a better confirmation of what it's asking. if i'm assuming correctly what it's asking, it's 625 different variations.
