Bingel [31]
Knowing that a square gives the optimum area; 

120=s²
√120=s 
√2×2×2×5×3=s
2√2×3×5=s
2√30=s 

Therefore, the length should be ≈10.95" 

Hope I helped :)

Hasan is painting a spherical model of a human cell for his science class. He uses 100π square inches of paint (in one coat) to
babymother [125]

Answer:

10 in

Step-by-step explanation:

So we want to consider the surface area of this sphere.

The formula for surface area of a sphere is A=4 \pi r^2.

So we have that the surface area is 100 \pi.

So I'm going to replace A in A=4 \pi r^2 with  100 \pi.

100\pi=4\pi r^2

Now our main objective here is to solve for r:

Divide both sides by 4 \pi:

\frac{100\pi}{4 \pi}=\frac{4\pi r^2}{4 \pi}

This gets us r^2 by itself:

25=r^2

What number squared gives you 25? If you don't know, just take the square root of both sides giving you:

\sqrt{25}=r

Now you can just put \sqrt{25} in your calculator.  You should get 5.

5 is the radius

The diameter is twice the radius.

So 2(5) is 10, so the diameter is 10 in.
