Question

Four Cylinder Concrete Pillar Supports the root or a building Each Pillars is 4cm long and 50cm In diameter

calculate the total volume of the four Pillars in m³​

Answer 1

Answer: The total volume of the four pillars is 0.251 cubic meters.

Step-by-step explanation: The volume of a cylinder is calculated by multiplying the area of its base by its height. The area of the base of a cylinder is calculated by multiplying the square of its radius by pi (π).

The radius of each pillar is half its diameter, so it’s 25cm.

The height of each pillar is 4m (400cm).

So, the volume of one pillar is π * (25cm)^2 * 400cm = 785398.16 cubic centimeters.

Since there are four pillars, the total volume is 4 * 785398.16 cubic centimeters = 3141592.64 cubic centimeters.

Since 1 cubic meter = 1000000 cubic centimeters, the total volume in cubic meters is 3141592.64 / 1000000 = 0.251 cubic meters.

Hop this helps, and have a great day! =)

Answer 2

the total volume is 0.0157 m³.

Explanation:

To calculate the total volume of the four concrete pillars, we need to find the volume of one pillar and then multiply it by four.

The volume of a cylinder can be calculated using the formula:

Volume = π * r^2 * h

Where:

π ≈ 3.14159 (pi, a mathematical constant)

r = radius of the cylinder

h = height of the cylinder

Given:

Diameter of each pillar = 50 cm

Radius (r) = Diameter / 2 = 50 cm / 2 = 25 cm = 0.25 m

Height (h) = 4 cm = 0.04 m

Now we can calculate the volume of one pillar:

Volume of one pillar = π * (0.25 m)^2 * 0.04 m

Calculating the above expression gives us:

Volume of one pillar = 3.14159 * (0.25 m)^2 * 0.04 m

= 3.14159 * 0.0625 m^2 * 0.04 m

= 0.00392699082 m^3

Since we have four pillars, we can multiply the volume of one pillar by four to get the total volume of the four pillars:

Total volume of the four pillars = 4 * 0.00392699082 m^3

≈ 0.01570796328 m^3
