Answer:
Step-by-step explanation:
circumference= 29.83
2 times 3.14 times radius
area=70.83
3.14 times radius squared
3. radius
4. Diameter
radius is 4.75
diameter is 9.5
not 100% sure on finding the angle measure. looks about 40 degrees
Answer:
243,000 people
Step-by-step explanation:
First, what we need to do is to calculate the area of the region using the 5-mile radius
Mathematically, we can calculate this as the area of a circle
Area = pi * r^2
Our r here is 5 miles
Area = pi * 5^2 = pi * 25 = 78.54 square miles
Now to get the population, we know that per square mile we have 3,100.
Hence per 78.54 square mile, we have 78.54 * 3100 = 243,273 people
To the nearest thousand, 243,000
Step-by-step explanation:
Soln,
Here,
45°+65°+y(let)=180°[ being a triangle]
or,110°+y=180°
or,y=180°-110°
so,y=70°
Now,
x=?
so,
x+y=180°[being straight angle]
or,x+70°=180°
or,x=180°-70°
x=110°
THEREFORE,x=110°
solved!
Answer:
The real zeros of f(x) are x = 0.3 and x = -3.3.

Answer:
<h2>z = 15</h2>
Step-by-step explanation:
<u>Cross multiply </u>
That's
<u>Send 15 to the right side of the equation</u>
Divide both sides by 15
We have the final answer as
<h3>z = 15</h3>
