Answer:
40 candles can be made from the wax.
Step-by-step explanation:
Diameter of each candle is 15 cm. Radius of each candle is 7.5 cm.
Volume of wax is [tex]70650\ cm^3[/tex].
Let there are x candles that can be made.
Candles are in the shape of solid sphere.
Volume of a sphere is given by :
[tex]V=\dfrac{4}{3}\pi r^3[/tex]
For x candles
[tex]V=x\times \dfrac{4}{3}\pi r^3\\\\70650= x\times \dfrac{4}{3}\pi r^3\\\\x=\dfrac{70650}{\frac{4}{3}\cdot3.14\cdot7.5^{3}}\\\\x=40[/tex]
So, 40 candles can be made from the wax.
