Answer:

V = 1436.8 in³

Step-by-step explanation:

The volume (V) of a sphere is calculated as

V = \frac{4}{3}πr³ ← where r is the radius

Here r = 7, so

V = \frac{4}{3}π × 7³ = \frac{4}{3}π × 343, that is

V = \frac{4(343)\pi }{3} ≈ 1436.8 in³ ( to the nearest tenth )

Rewrite 19/19 as a whole number
Elis [28]

The answer is 1.

Because if you simplify (divide) 19/19 you get one.

4/4 would also be 1.  Any number divided to itself will always be 1.

Whereas 30/15 would be 2 because thirty divided by fifteen is 2

In B E C, F is the centroid, and AC = 12. Find A F and F C
klemol [59]

bearing in mind that the centroid in a triangle cuts each of the three medians in a 2:1 ratio.

since we know that A C = 12, let's split it in a 2:1 ratio then, cleary from the picture the larger is F C, so F C : A F is on a 2:1 ratio.

\bf A C=A F+F C\qquad \qquad \cfrac{F C}{A F}=\cfrac{2}{1}\qquad \qquad \cfrac{2\cdot \frac{12}{2+1}}{1\cdot \frac{12}{2+1}}\implies \cfrac{2\cdot 4}{1\cdot 4}\implies \cfrac{8}{4}
