Answer:
The candle will not use all the paraffin from the original block.
Step-by-step explanation:
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.
Answer:
90
Step-by-step explanation:
The angle formed outside = 1/2(difference of intercepted arcs)
The large arc is 360-x and the inner arc is x
x = 1/2 (360 -x - x)
x = 1/2 (360 -2x)
Multiply each side by 2
2x = 360 -2x
Add 2x to each side
2x+2x = 360
4x= 360
Divide by 4
4x/4 = 360/4
x = 90
1 / 4 of 28
it means 1 / 4 x 28
= 28 /4
= 7
