What is the minimum side length of clipboard that Anna could use that the whole sheet of paper? A 9 in B. 27 in C. 182.25 in. D. 364.5 in. Based on this information, what is the approximate volume of this cone? A 80 27 A basketball has a diameter of 9.5 cm B. 40 pl C. 80 pi D. 120 pl Which of the expressions shows how determine the volume of all the bash hold?

Answer 1

step 1

Find out the radius

Applying the Pythagorean Theorem

6^2=4^2+r^2

r^2=36-16

r^2=20

`r=2\sqrt[]{5}\text{ in}`

The volume of the cone is equal to

`V=(1)/(3)\cdot\pi\cdot r^2\cdot h`

substitute the given values

`\begin{gathered} V=(1)/(3)\cdot\pi\cdot(2\sqrt[]{5)}^2\cdot4 \\ V=(80)/(3)\pi\text{ in\textasciicircum{}3} \end{gathered}`

therefore

answer is option A
