The height of a cone is two times its base diameter. What is the volume of the cone in terms of its base radius r?​

Mathematics

Fudgin [204]2 years ago

Answer:

B

Step-by-step explanation:

Formula for finding the volume of a cone:  V=\pi r^{2} \frac{h}{3}

From the question, we can tell that the height, h, is equal to 2d or 4r.

h = 4r.

Substitute h into the volume formula:

V=\pi r^{2} \frac{4r}{3}

Rearrange to get the final equation of:

V=\frac{4}{3} \pi r^{3}

Sara is mixing together a fruit punch for a party. She's made 4 gallons of punch with a mixture of 50% juice. Her mother tells h
Nata [24]
\bf \begin{array}{lccclll}
&amount(gallons)&juice&\textit{juice amount}\\
&--------&-----&-----\\
\textit{50\% punch}&4&0.50&(4)(0.50)\\
\textit{pure juice}&x&1.00&(x)(1.00)\\
-----&-----&-----&-----\\
mixture&4+x&0.60&(4+x)(0.60)
\end{array}

notice, that, pure juice is 100% juice, dohhh, thus 100/100 = 1.00
50% is 50/100 or 0.50 in decimal format

so..... whatever those two quantities amount to, that is, the 50% and pure juice, or (4)(0.50) + (x)(1.00)
they will equal the mixture desired 60% juice, or 0.60, namely (4+x)(0.60)

thus    (4)(0.50) + (x)(1.00) = (4+x)(0.60)

solve for "x"

Estimate each the quotient 78÷4 is about _____÷4
KonstantinChe [14]

Answer:

80

Step-by-step explanation:

The trick is to pick something that should be very easy to get an answer to. If you use a calculator, you are not estimating.  80 divide by 4 is like 8 divide by 4 which gives you 2. Then just add a zero. Here's another one you can try. Put your calculator away to do it. 12 chicken noodle  soup cans cost 14 dollars. About how much does 1 can cost

no cheating. No calculator. Is the cost of 1 can more or less than a dollar? If you said more, you've estimated correctly.

Try it the other way. Suppose one can of the soup costs 0.95 cents. How many will 12 cans cost? More or less than 12 dollars.

If you said less, you are estimating correctly. The most useful gift you can take away from any math class is estimation.
