Answer:
r=12.7323
Step-by-step explanation:
We find out the arc length formula when multiplying this equation by Θ:
Θ=45 degrees=π/4
L = r * Θ
r=L/Θ=10/π/4=40/π=12.7323
this answer is for sector(part of a circle)
Answer:
In 42 years from now the population would be 6,000
Step-by-step explanation:
Answer:
15 in^2
Step-by-step explanation:
Find the area of the vertical rectangle
A = l*w
A = 6*2 = 12 in^2
Now find the area of the horizontal rectangle
A = l*w
= 3*1 = 3in^2
Add them together
12+3 =15 inch^2
Since we know a triangle only has 180 degrees we can say:
99+3x+x+5=180
Then we can solve for x:
4x+104=180
4x=76
x=19
