Find the height h of a cone with volume V = 32π cm3 and radius r = 4 cm.
1 answer:
The height of the cone is 6 cm.
Step-by-step explanation:
Given,
Volume of cone = V = 32π cm³
Radius of cone = r = 4 cm
Height of cone = h
It's known that;
Volume of cone =
Substituting the values into the equation
Dividing both sides by 16π
Multiplying both sides by 3
The cone’s height measures 6 cm.

Answer:
3.5
Step-by-step explanation:
For a shape that is half a circle, use the formula: A = π
Calculate the radius, which is half of the diameter: r = d/2 = 3/2 = 1.5
Insert r = 1.5 into the formula.
A = π
A = (3.14)
Calculate the result with your calculator and round it off.
The final answer is 3.5
