Answer:
Step-by-step explanation:
we are given triangle as
we know that
triangle PRS and triangle PQS are similar
so, the ratios of their sides must be equal
we get
now, we are given
RS=4
QS=6
we can plug it
now, we can solve for PS
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
