To calculate the volume of a cylinder, you need to use the formula V = πr²h, where V is the volume, π is a mathematical constant approximately equal to 3.14159, r is the radius of the base, and h is the height.
Given that the base diameter is 4m, the radius (r) can be calculated by dividing the diameter by 2:
r = 4m / 2 = 2m
Now we can substitute the values into the formula:
V = π(2m)²(8m)
V = π(4m²)(8m)
V = 32πm³
To round the volume to the nearest tenth, we can use the approximate value of π as 3.14159:
V ≈ 32 × 3.14159 ≈ 100.53096m³
Rounding to the nearest tenth:
V ≈ 100.5m³
Therefore, the volume of the cylinder is approximately 100.5 cubic meters.
I hope this helps! :)
