Alex has 520 yards of fencing to enclose a rectangular area.

Pavlova-9 [17]

<span>Perimeter =2w+2L= 520.
We can solve this by understanding that the area is maximized by a square
Therefore L=w.

p=2w+2w=520=4w
w=130

Area

A=wL=130(130)= 16900 square yards</span>

Hal says the volume of the sphere shown below 36 cm3. Find the correct volume, using 3.14 for pi. Round to the nearest hundredth

adelina 88 [10]

Answer:

Volume of sphere is $35.98cm^3$

Step-by-step explanation:

It is given that Hal says that volume of sphere is $36cm^3$

Volume of sphere is given by $V=\frac{4}{3}\pi r^3$

$\frac{4}{3}\pi r^3=36$

$\pi r^3=27$

$r^3=8.594$

$r=2.048cm$

Now using 3.14 in place of $\pi$

Now volume of sphere is

$V=\frac{4}{3}\times 3.14\times 2.048^3$

$V=35.98cm^3$

Therefore volume of sphere when we use 3.14 in place of $\pi$ is $35.98cm^3$

And the Hal likely error is he uses $\pi$ directly for calculation of volume.
