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.

Justin took a quiz with five multiple choice (A-D) and five true/false questions. How many different ways can he answer the ques

ankoles [38]

Answer:

32,768 ways

Step-by-step explanation:

True/ false questions = 5 ; number of options = 2 (True or false)

Ways of answering = 2^5 = (2 * 2 * 2 * 2 * 2) = 32

Number of Multiple choice questions = 5

Number of options (A - D) = 4 options

Ways of answering = 4^5 = (4 * 4 * 4 * 4 * 4) = 1024

32 * 1024 = 32,768 ways
