Answer:
24.76 mine
Step-by-step explanation:
The first thing is to calculate the area of the region, which we can calculate since we have the density and the population. The area would be the quotient between population and density:
260000/135 = 1925.93
The area would be 1925.93 square mine
We know that the area is given by:
A = pi * r ^ 2
we solve to r
r ^ 2 = A / pi
r ^ 2 = 1925.92 / 3.14
r ^ 2 = 613.3
r = 24.76
the radius is equal to 24.76 mine
Answer:
5^5-7^2= 3076
Step-by-step explanation:
5^5=3125
5*5*5*5*5
7^2=49
3125-49=3076

Answer:
Larger shaded area = 48pi m^2 and
the small circle has area 4pi m^2.
If you require the as decimal values they are
150.80 m^2 and 12.57 m^2 to the nearest hundredth.
Step-by-step explanation:
The area of the whole circle = pi r^2 = pi 8^2 = 64pi.
The area of the middle sized circle = pi 4*2 = 16pi.
So the area of the larger shaded region
= 64pi - 16pi = 48pi m^2.
The area of the small circle = pi r^2 = 2^2 pi = 4pi m^2.
