We know that
[the area of a circle]=pi*r²
for r=4 ft
[the area of a circle]=pi*4²------> 50.24 ft²
if 2π radians ( full circle) has an area of-----------------> 50.24 ft²
5π/2 radians--------------------------------------> X ft ²
X=(5π/2)*50.24/2π-------> 62.8 ft²
the answer is
62.8 ft²
Answer:
Step-by-step explanation:
160miles • 330miles= 52,800square miles
Now it wants the population density in people per square miles, so you need to divide the population by the number of square miles.
4779736/52800=90.5 which is about 91people per square mile.
Answer:
8.7
Step-by-step explanation:
To find the mean first you have to add up all the weight of the cats which is:
After, you have to divide the total weight by the number of cats there are
which is: 
Since, this is a really long number you would normally round the number to the nearest tenth which is 8.7
