Answer:
3.05 yards
Step-by-step explanation:
Arc length= 2π(r)(Θ/360)
given: 7 yards is diameter, 50 degrees
radius= diameter/2 = 3.5
plug in
2π(3.5)(50/360) = 3.05 yards
Divide 20.8 by 11.2 to get 1.86
Answer:
22 pi ft
Step-by-step explanation:
We can use the area to find the radius
A = pi r^2
121 pi = pi r^2
Divide each side by pi
121 = r^2
Take the square root
sqrt(121) = sqrt(r^2)
11= r
Now we need to find the circumference
C = 2*pi*r
C = 2* pi *11
C = 22 pi ft

Call the first even number '2n'
Thus, the next would be 2n + 2
And the next would be 2n + 4
Form an equation:
2n + 2n + 2 + 2n + 4 = 36
Simplify:
6n + 6 = 36
Subtract 6 from both sides:
6n = 30
Divide both sides by 6:
n = 5
2(5) = 10
The smallest number is 10
