Answer: C. 5.8 inches
Step-by-step explanation:
The formula for calculating the Surface area of a cube is give as :
surface area = 6
Where a is the length of an edge
That is :
200 = 6
divide through by 6
200/6 =
that is
= 33.33333333
take the square root of both sides
a = 5.773502692
Therefore the length of an edge ≈ 5.8 inches
Answer:
4π ≈ 12.5663706144
Step-by-step explanation:
The circumference of a circle is 2πr, or 2*pi*radius
Suppose the circle has a diameter of 4 inches. A diameter is 2x the radius, of which we are looking for, therefore:
4÷2=<u>2 inches</u> (radius length)
Now that we have the radius, let us <u>substitute</u> to find the circumference:
2πr=
2π2=
4π≈
<u>12.5663706144</u>
<u></u>

Answer:
b = -12
Step-by-step explanation:
First isolate b by subtracting 2 from both sides: b/4 = -3
then multiply both sides by 4 to find b: b = -12
I think it would be 46.00 pounds
