Find the the volume of a cone with the radius of 5ft and a height of 12ft
If you have 3 questions on the Measurement Unit Review Practice the 3 answers are
1. 64,288 ft3
2. 2,713 yd3
3. 314 ft3
r = 5 ft
h = 12 ft
V = r² ∙ π ∙ h / 3
V = 5² ∙ π ∙ 12 / 3
V = 25 ∙ π ∙ 12 / 3
V = 300 π / 3
V = 100 π = 314.159 ft³
ok i have 3 questions....
thxs
thank you!!
effects is correct as of december 15th 2022 11:50 am. thanks os much
To find the volume of a cone, you can use the formula:
V = (1/3) * π * r^2 * h
where V represents the volume, π is a mathematical constant (approximately equal to 3.14159), r is the radius of the cone's base, and h is the height of the cone.
Given that the radius (r) is 5ft and the height (h) is 12ft, let's substitute these values into the formula:
V = (1/3) * π * 5^2 * 12
First, calculate 5^2, which equals 25:
V = (1/3) * π * 25 * 12
Next, multiply 25 by 12:
V = (1/3) * π * 300
Lastly, multiply π by 300 and divide the result by 3:
V ≈ (1/3) * 3.14159 * 300
V ≈ 942.48 cubic feet
So, the volume of the cone is approximately 942.48 cubic feet.
