What is the volume of a cylinder with radius 8km and height 7km?
recall that the volume of a cylinder is given by
V = pi*r^2*h
where
r = radius
h = height
substituting,
V = pi*(8^2)*(7)
V = 3.14*64*7
V = 1407.43 cubic km
hope this helps~ :)
why this no help =_=
To calculate the volume of a cylinder, you can use the formula:
Volume = π * radius^2 * height
Given that the radius is 8 km and the height is 7 km, we can substitute these values into the formula:
Volume = π * (8 km)^2 * 7 km
First, let's calculate the square of the radius:
Volume = π * (64 km^2) * 7 km
Now, let's simplify the expression further:
Volume = 448π km^3
The volume of the cylinder is 448π km^3.
To find the volume of a cylinder with a given radius and height, you can use the formula:
Volume = π * radius^2 * height
In this case, the radius is 8km and the height is 7km. First, we need to square the radius:
Radius^2 = 8km * 8km = 64km^2
Then, we can substitute the values into the formula:
Volume = π * 64km^2 * 7km
To calculate the volume, we also need the value of π (pi). Pi is a mathematical constant with an approximate value of 3.14159.
Volume ≈ 3.14159 * 64km^2 * 7km
Now, we can calculate the volume by multiplying these values together:
Volume ≈ 3.14159 * 64km^2 * 7km
Volume ≈ 14049.97 cubic kilometers
Therefore, the volume of the cylinder is approximately 14049.97 cubic kilometers.
