Justin bought a calculafor and a binder that were both 15% off the original price. The original price of the binder was $6.20. J

mash [69]

6.20 x .15 = .93
6.20-.93= 5.27
107.27-5.27=102
102 x .15 = 15.3
102+15.3=117.3
$117.3

Find the volume of this sphere. Please help

natulia [17]

Hello there!

We've already given the formula so I will not be adding it here.

We are also given that π = 3 for this problem.

r is defined as 'radius'

Radius is a point from center to one of endpoints.

Look at the image, the radius is given as 7cm.

From the information we gathered:

π = 3
r = 7

Substitute in the formula.

$\displaystyle \large{ V = \frac{4}{3} (3) {(7)}^{3} }$

Cancel 3 out.

$\displaystyle \large{ V = 4{(7)}^{3} }$

Evaluate 7^3

$\displaystyle \large{ V = 4(343) }$

Multiply

$\displaystyle \large{ V = 1372 }$

Therefore, the volume is 1372.

Let me know if you have any questions!
