The radius of a baseball is about 9.25 inches. The radius of the Basketball is 9.55 inches. What is the

yuradex [85]

Answer:

C. 333.14

Step-by-step explanation:

Both the basketball and baseball has got the shape of a sphere. So that;

volume of a sphere = $\frac{4}{3}$ $\pi$ $r^{3}$

where r is the radius

i. Volume of the baseball = $\frac{4}{3}$ $\pi$ $r^{3}$

= $\frac{4}{3}$ x $\frac{22}{7}$ x $(9.25)^{3}$

= 3315.5655

volume of the baseball = 3316.57 cube inches

ii. Volume of the basketball = $\frac{4}{3}$ $\pi$ $r^{3}$

= $\frac{4}{3}$ x $\frac{22}{7}$ x $(9.55)^{3}$

= 3649.8372

Volume of the basketball = 3649.84 cube inches

The required difference = volume of basketball - volume of baseball

= 3649.84 - 3316.57

= 333.27 cube inches

The difference of the volumes of the basketball and baseball is 333.27 cube inches.

Find the exact area of a circle having the given circumference. 4(√3 π) A =

Alik [6]

$\bf \textit{circumference of a circle}\\\\
C=2\pi r\qquad 
\begin{cases}
r=radius\\
----------\\
C=4\sqrt{3}\ \pi 
\end{cases}\implies 4\sqrt{3}\ \pi=2\pi r
\\\\\\
\cfrac{4\sqrt{3}\ \pi}{2\pi}= \boxed{r}\\\\
-----------------------------\\\\
\textit{area of a circle}\\\\
A=\pi r^2\qquad \boxed{r}=\cfrac{4\sqrt{3}\ \pi}{2\pi}\implies A=\pi \left( \cfrac{4\sqrt{3}\ \pi}{2\pi} \right)^2$

Determine the slope of the line.

Akimi4 [234]

Answer:

Step-by-step explanation:

→ Find 2 points from the line

( 0 , 6 ) and ( - 3 , 0 )

→ Find the change in y coordinates

0 - 6 = -6

→ Find the change in x coordinates

-3 - 0 = -3

→ Divide the 2 results

-6 ÷ -3 = 2

Ok, so you know that we can't divide fractions no matter what. The first thing you do is keep the first fraction, then change the divide sign to multiplication ( opposite of division is multi. ) and finallly flip the last fraction to 7/1 .

Here's a video to help you understand that method more ...
