OK, no figure, but from the comment is sounds like the grey area is the big circle minus the small circle.
The diameter of the small circle is 2 so its radius is 1 and its area πr² is π.
The radius of the larger circle is 4, so area 16π
The shaded area is 16π - π
Answer: 15π
1000 x 5 = 5000
Lana's dad would take about 5000 steps.
5000 x 2 = 10,000
Lana would take about 10,000 steps.
Glad I could help, and good luck!
If the figure is drawn in a 2/5 scale, this means that all the length will be multiplied by 2/5. The area is a two-dimensional thing, so it would be multiplied by that factor twice, or 4/25. You can try checking all the lengths. The correct one should match all of the things I said above.
The answer is the top left one.
Answer:
Step-by-step explanation:
let x and y be the distances of each car from the intersection after sometime.
let x<y
then y-x=7
and y+x=13
add 2y=20
y=10
x=13-10=3
slower car travels 3 miles and faster car travels 10 miles
