Question

Susan makes a trundle wheel. the radius of the wheel is 0.2 meters. she pushes the wheel across the playground. the wheel makes 30 complete revolutions. find the distance across the playground.
pi is 3.14​

Answer 1

Answer:

37.68 meters

Step-by-step explanation:

okay so in this question, you need to find out the circumference of the wheel, that is the distance that the wheel covers if u cut it and laid it flat down. so then to find the circumference when given a radius would be to use the equation 2(pi)r

so then the circumference is .2*2*3.14 = 1.256meters.  

now thats the distance covered if the wheel went around one revolution so in 30 revolution, you multiply it by 30 so then

1.256*30  = 37.68 meters, give or take because the calculator's pi is more than just 3.14. but overall the answer is 37.68 meters.
