14/10 = 140%
The correct answer for the question that is being presented above is this one: "B.a circle with a radius of 4 in." <span>circles have an area of16 pi in2 should have a radius of 4 in.
</span>
The area of a circle is this:
Area = pi * r^2
16 pi = pi * r^2
r^2 = 16
r = 4.
Answer:
Relation #2 and #4
412 ÷ 20 = 20 boxes with 12 remaining.
Total boxes needed = 20 + 1 = 21
Answer: 21 boxes will be needed.
Answer:
30
Step-by-step explanation:
So we begin by assigning variables to each side with:
DE = x
EF = y
DF = z
Now we start listing a system of equations from what is given:
x+y+z=81
x=2y
x-4=z
Once we solve that with substitution, we get the result of:
x=34
y=17
z=30.
Since z is the length of DF, the length of DF is 30.
I hope this helped! :D
