<span>In geometry, a diameter of a circle is any straight line segment that passes through the center of the circle and whose endpoints lie on the circle. It can also be defined as the longest chord of the circle. Both definitions are also valid for the diameter of a sphere.</span>

Answer:

w = 12

Step-by-step explanation:

We are given the equation:

$\displaystyle{\dfrac{w-2}{4} = \dfrac{2w+1}{10}}$

First, clear out the denominators by multiplying both sides by LCM. In this scenario, our LCM is 40. Thus, multiply both sides by 40:

$\displaystyle{\dfrac{w-2}{4} \cdot 40= \dfrac{2w+1}{10} \cdot 40}$

Simplify the expressions/equations:

$\displaystyle{(w-2)\cdot 10= (2w+1)\cdot 4}\\\\\displaystyle{10w-20= 8w+4}$

Isolate w-variable:

$\displaystyle{10w-20= 8w+4}\\\\\displaystyle{10w-8w=4+20}\\\\\displaystyle{2w=24}\\\\\displaystyle{w=12}$

Hence, the solution is w = 12

Answer:

$\displaystyle {r}^{} = 6$

Step-by-step explanation:

remember that,

$\displaystyle V _{ \rm sphere} = \frac{4}{3} \pi {r}^{3}$

given that,

V=288π

thus substitute:

$\displaystyle \frac{4}{3} \pi {r}^{3} = 288\pi$

divide both sides by 4/3π:

$\displaystyle {r}^{3} = 216$

cubic root both sides:

$\displaystyle {r}^{} = 6$

and we are done!
