What is the volume of the cone?
1 answer:
Answer:
The volume of the cone is 75.36 cm³
Step-by-step explanation:
The rule of the volume of a cone is V = π r² h, where
- r is the length of the radius of its base
- h is the height of the cone
In the given figure
∵ The length of the radius of the cone is 3 cm
∴ r = 3 cm
∵ The length of the height of the cone is 8 cm
∴ h = 8 cm
→ Substitute the values of r and h in the rule of the volume above
∵ π ≅ 3.14
∵ V = (3.14)(3)²(8)
∴ V = 75.36 cm³
∴ The volume of the cone is 75.36 cm³

Answer:
The number is 6
Step-by-step explanation:
Given:
A number tripled and 6 is 24
To Find:
The Number = ?
Solution:
Let the number be x
The question states that the number is tripled. so lets multiply the number by 3, We get
3x
Then
3x + 6 = 24
On solving the equation we get
3x = 24 -6
3x = 18
x = 6
