Well first, we must remember the formula for the area of a circle.
The formula for the area of a circle is:
PiR^2, or Pi • R^2.
Basically this means 3.14 (Pi) • R • R (Radius).
We have our radius, 4, so we can plug in our numbers to solve.
3.14 • 4 • 4 is our formula, so let's solve.
4 • 4 = 16.
16 • 3.14 = 50.24.
Remember when we solve for the area, we use units squared (units^2).
Your answer is 50.24 cm^2.
I hope this helps!
Answer:
10 years
Step-by-step explanation:
Let c and s represent the populations of Canyon Falls and Swift Creek, respectively. For time t in years, the respective populations are ...
c = 22500 -740t
s = 15200 +1500t
We want to find t when s = 2c.
s = 2c
15200 +1500t = 2(22500 -740t)
2980t = 29800 . . . . . add 1480-15200, simplify
29800/2980 = t = 10 . . . . divide by the coefficient of t
The population of Swift Creek will be double that of Canyon Falls in 10 years.
This will be from least to greater -1 -2 4 5
Answer:
+112 +11v
Step-by-step explanation:
-7(-10-6)+1v+10v =
(-10-6) = -16
-7(-16) +1v +10v =
+112 +1v +10v =
+112 +11v
500 divided by 60 = 8.33... (but you round it to 8)
it would take her about 8 minutes.
