Answer:
A. 3 cm
Step-by-step explanation:
The smallest face has the sides 4 cm and 8 cm. If the water is 4 cm from its top, then the height of the water is cm and the volume of the water is
The largest face has the sides 8 cm and 16 cm. If the container is placed on its largest face, then the volume of the water is
where h is the height of the water.
Equate volumes of the water:
Therefore, the water is 3 cm from the bottom.
Answer:
12.4 cm³
Step-by-step explanation:
From the picture attached,
Radius of the circular top of the cone = =
Height of the cone = h
Lateral height of the cone = h
By applying Pythagoras theorem in the right triangle of the cone,
l² = r² + h²
6² = 1² + h²
h =
h =
Ice cream needed to fill one cone = Volume of the cone
Since, formula for the volume of the cone V =
V =
= 6.195
≈ 6.20 cm³
Ice cream needed to fill the two cones = 2 × 6.20
= 12.4 cm³
Therefore, ice cream needed to fill the two cone = 12.4 cm³
