William pushed a shopping cart at a steady speed for 9.0seconds. The cart moved 9.9meters in that time. What was the cart's speed?

1.1 meters/second

Step-by-step explanation:

Speed = the magnitude of distance / time

Distance = 9.9 meters

Time = 9.0 seconds

Speed = 9.9 meters / 9.0 seconds = 1.1 meters/second

both equations and proportions are better.

circle area = pi * radius^2

if diameter = 10 then radius = 5

circle area = pi * 5^2

circle area = pi * 25

circle area = 78.5398163397 square units
