Answer 1

Answer:

Step-by-step explanation:

The candle is cylindrical in shape.

The formula for determining the volume of a cylinder is expressed as as

Volume = πr²h

Where

π = 3.14

r represents radius of the cylinder and also the candle

h represents the height of the cylinder and also the candle.

Looking at the diagram,

r = 4 cm

h = 6 cm

Volume of candle = 3.14 × 4² × 6

= 301.44 cm³

Looking at the table,

60 cm³ of the candle melts off in 2 hours, it means that the in one hour, the volume of candle that melts off would be 60/2 = 30cm³

Therefore, in 7 hours, the volume of candle that would melt off is

30 × 7 = 210 cm³

Therefore, the percent of candle that is melted off after 7 hours would be

210/301.44 × 100 = 69.67%

Approximately 70% to the nearest percent.

Answer 2

Answer:

After 7 hours about 70% of the candle was melted
