10. Find the volume of the right cone pictured here. (Give your answer correct to 1 decimal place.)

Answers

Volume = 49.7pi

The volume of a cone can be found with the following equation

[tex]V = r^2\frac{h}{3} \pi[/tex]

From here we can solve the equation

[tex]V = 3.4^2\frac{12.9}{3} \pi \\V = 11.56 * 4.3 \pi \\V = 49.7 \pi[/tex]

Jordyn got 15 out of 20 questions correct on her quiz. What percent did she get correct? (Provide the % symbol in your answer)

Answers

Answer:

75%

Step-by-step explanation:

Hello!

I'd love to help.

An easy method to finding a percentage is converting it into a decimal.

First though, we must simplify 15/20, which would be 3/4, (please let me know if you need the process of simplification)

Then we find the decimal.

We divide the numerator by the denominator.

3 ÷ 4 = .75

Which means that our final answer is:

75%

Now, you will look at each chart for 3 x's above the number 4. You have now eliminated the middle two. Next, count how many 3's there are, which is 2. Both have those, so eliminating other choices is a no-go. Now, look at how many 5's you have, which is 2. Look at your charts... again, no choice ca be marked-off. Finally, look at how many 6's there are, which is 3. So, look at your last options and find which one has 3 total x's above the 6. And there you go, D.
