Answer:
440m^2
Step-by-step explanation:
15400/(22/7)=4900, which is r^2, so r=70. Now we can find the circumference by doing 22/7*2*70, which is 440.
Find the radius of the circle:
Area of a circle = pi x r^2
15,400 = 22/7 x r ^2
Divide both sides by 22/7
4900 = r^2
Take the square root of bothe sides:
R = 70
The radius of the circle is 70 meters.
now find the circumference:
Circumference = 2 x pi x radius
Circumference = 2 x 22/7 x 70
Circumference = 440 meters
answer: 440 meters
omg were u taking a test lol
i am not good with math but b i think.
see image
60 mintues
1/6 of 60= 6
10 hours= 600 minutes
600÷6= 60 mintues
Density per square block means the area:
Area = Length x width = 2 x 2 = 4 square blocks.
Now for density divide the population by the area:
1.5 million people / 4 square blocks = 0.375 million people per square block
0.375 million = 375,000
