Answer:

17. 5

18. 17

Step-by-step explanation:

The distance formula is used for the purpose.

d = √((x2 -x1)² +(y2 -y1)²)

17. d = √((3-6)² +(1-5)²) = √((-3)² +(-4)²) = √(9+16) = √25 = 5

The distance between the points is 5 units.

18. d = √((-1-7)² +(12-(-3))²) = √(64 +225) = √289 = 17

The distance between the points is 17 units.

A candle maker has rectangular block of paraffin that is 4 centimeter high by 8 centimeter long by 6 centimeter wide. He melts i

Veronika [31]

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

$\frac{1}{3}\pi r^{2} h$

= $\frac{22 \times 2.5^{2} \times 25 }{3 \times 7}$

= 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.
