Which is the best approximation of the volume of a cylinder with a radius of 10 mm, and a height of 5 mm?
To find the volume of a cylinder, you can use the formula V = π * r^2 * h, where V is the volume, π is the mathematical constant pi, r is the radius, and h is the height of the cylinder.
In this case, the radius is 10 mm and the height is 5 mm. Let's substitute these values into the formula:
V = 3.14 * (10 mm)^2 * 5 mm
First, let's calculate the value of (10 mm)^2, which is (10 mm) * (10 mm):
(10 mm)^2 = 100 mm^2
Now let's substitute this value back into the formula:
V = 3.14 * 100 mm^2 * 5 mm
Next, let's multiply the numbers and units:
V = 314 mm^2 * 5 mm
Multiplying these values:
V = 1570 mm^3
Therefore, the best approximation of the volume of the cylinder is 1570 mm^3.
