Answer:
Option (2)
Step-by-step explanation:
From the picture attached,
When the given shape is rotated about the axis 'a',
Triangle ABC forms a 3-D figure of a cone.
Segment AB is the diameter of the circular base and CD is the height of the cone.
Therefore, Option (2) CONE will be the answer.
Answer
Find out the how many of each metal did your team win.
To prove
As given
Your team wins 18 medals at a competition.
The metals are gold, silver, and bronze in a ratio of 2:4:3.
Let us assume that x be the scalar multiple of the gold, silver and bronze medal.
Thus
Number of gold medal = 2x
Number of silver medal = 4x
Number of bronze medal = 3x
Than the equation becomes
2x + 4x + 3x = 18
9x = 18
x = 2
Number of gold medal = 2 × 2
= 4
Number of silver medal = 4 × 2
= 8
Number of bronze medal = 3 × 2
= 6
Therefore the number of gold medal are 4, silver medal are 8, bronze medal are 6.
Answer:
The volume of the cylinder is 163.3 m³.
Step-by-step explanation:
Given that,
Height = 13 cm
Base = 4 cm
So, radius = 2 cm
We need to calculate the volume of the cylinder
Using formula of cylinder
Where, r = radius
h = height
Put the value into the formula
Hence, The volume of the cylinder is 163.3 cm³.
