LuckyWell [14K]

If you divide 20 acres into 1/4 sections you'll get
20 ÷ 1/4 sections. When you divide fractions, you just multiply the reciprocal.

20 ÷ 1/4 =
20 × 4/1 = 80 sections

The volume of a beack ball is 905 square centimeters. Find the radius of the ball to the nearest whole number.

lubasha [3.4K]

<h3>given:</h3>

$v = 905 \: {cm}^{3}$

the radius of the given ball (sphere).

<h3>solution:</h3>

$r = \sqrt[3]{ \frac{3v}{4\pi} }$

$r = \sqrt[3]{ \frac{3 \times 905}{4\pi} }$

$r = 6 \: cm$

therefore, the radius of the ball is 6 cm.

note: refer to the picture I added on how you can change r as the subject of the formula.

More math help please!

Nata [24]

AS we know that:

$V=SA*h$

And we have the volume and we can calculate the SA,,,

So that, we can conclude:
$h= \frac{V}{SA} = \frac{323.5}{\pi (7)^2} =2.1015~~in$

Are you satisfied?
