we have different side lengths and thus different angles anyhow, meaning is an Scalene triangle.

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

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.

Answer:

$\mathrm{12\sqrt{5} \: \: inches}$

Step-by-step explanation:

Use Pythagorean theorem, where:

$a^2+b^2=c^2$

Substitute in the values.

$24^2+12^2=c^2$

$c^2=576+144$

$c^2=720$

$c=\sqrt{720}$

$c=12\sqrt{5}$

$c=26.83281$
