Answer:
D
Step-by-step explanation:
The candle will not use all the paraffin from the original block.
The cone-shaped candle is 5 cm wide at the base i.e. the diameter of the base is 5 cm i.e. radius is 2.5 cm.
If the height of the cone is 25 cm, then total volume of the cone shaped candle is
=
= 163.69 cubic cm.
Again, the volumes of the rectangular block of paraffin is (4 × 8 × 6) = 192 cubic cm.
Since, 192 > 163.69
Therefore, the candle will not use all the paraffin from the original block.
wow.
Multiply and divide by the conjugate.
The conjugate is the denominator with the sign of the complex number the opposite of the denominator.
