second question:

circumference = 2*π*r or d(diameter)*π

A car travels 32 miles for each gallon of gas.How many gallons of gas does it need to travel 192 miles

gladu [14]

Hi there! :)

Answer:

The car needs 6 gallons of gas to travel 192 miles.

Step-by-step explanation:

In order to answer your question, you'll need to use the cross product method:

32 miles → 1 gallon

192 miles → X gallons

(1 × 192) ÷ 32 = X gallons

192 ÷ 32 = X gallons

6 = X gallons

There you go! I really hope this helped, if there's anything just let me know! :)
