Volume of the candle:
V = B * h ( where B is the base area and h is the height )
270 = B * 18
B = 270 : 18
B = 15 cm²
B = a * b / 2
B = 5 * b / 2
15 = 2.5 b
b = 15 : 2.5
b = 6 cm
Therefore dimensions of the box are: a = 7cm, b = 6 cm, c = 18 cm.
Answer: B ) 7 by 6 by 18 cm.
YES if you simplify 15:10 by 5 since they can both be divided by 5 the ratio becomes 3:2
1.) .777777778
2.) .8
3.) .6
4.) .285714286
5.) .15
Answer:
C. 81π cm³
Step-by-step explanation:
The volume of the cylinder is found using the volume formula:
V = πr²h
where r is the radius and h is the height.
__
<h3>application</h3>
For the cylinder shown, the radius is r = 3 cm, and the height is h = 9 cm. Then the volume is ...
V = πr²h = π(3 cm)²(9 cm) = 81π cm³ . . . . matches choice C
