First, use the equation for circumference:
c= 2πr
now plug in what you know:
c= 2π(4.5)
c= 9π
Answer:
15 days
Step-by-step explanation:
We can use a ratio to solve
4 bird houses 20 bird houses
--------------------- = -------------------------
3 days x days
Using cross products
4x = 3*20
4x = 60
Divide each side by 4
4x/4 = 60/4
x = 15
15 days
Answer:
Example a) the resulting vector is 54 degrees with a force of 48N (4.8cm)
Example b) the resulting vector is 168 degrees with a force of 38N
Example c) the resulting vector is 129 degrees with a force of 57N
Step-by-step explanation:
i had the same assignment so i used the vector calculator online
D=√(6-0)²+(2-10)²
d=√(6)²+(-8)²
d=√36+64
d=√100
d=10
