The graph with the line going through (0,0) with a slope of 2. This is because for every 1 hour, she has 2 bags of leaves.
The y number goes up by 2. 0 hours, 0 bags. 1 hour, 2 bags. 2 hours, 4 bags. And so on.
(0,0), (1,2), (2,4), (3,6)...
Hey there! I'm happy to help!
First, let's find the radius. The radius is half of the diameter.
8.4/2=4.2
Here's how to find the area of a circle.
Square the radius.
4.2²=17.64
And multiply by pi (3.14 in our case)
17.64(3.14)=55.3896
We round to the nearest tenth, giving us an area of 55.4 ft²
Have a wonderful day! :D
