Find the volume of the sphere. <br> Either enter an exact answer in terms π or use 3.14 for π

Lunna [17]

The equation for volume of a sphere is (4/3)(pi)(r)^3. So you would plug in he radius 9 into the equation. It would simplify to equal (4/3)(pi)(729). It simplifies further to equal (972)(pi)

Someone please help me with this.

Radius=r=0.7m
Volume=231m^3
Height=h

$\boxed{\sf Volume=\pi r^2h}$

$\\ \sf\longmapsto π(0.7)^2h=231$

$\\ \sf\longmapsto 0.49πh=231$

$\\ \sf\longmapsto πh=\dfrac{231}{0.49}$

$\\ \sf\longmapsto 3.14h=471.4$

$\\ \sf\longmapsto h=\dfrac{471.4}{3.14}$

$\\ \sf\longmapsto h=150m$

To complete the square, you take half of the coefficient of b and square it. It's important to note that the value being added will always be positive.

${ax}^{2} + bx + c$

$b = - 6$

$- 6 \div 2 = - 3$

$= {( - 3)}^{2}$

$= 9$
