Question

The pillars of a temple are cylindrically shaped. If each pillar has a circular base of radius 20 cm and height 10 m. How much concrete mixture would be required to built 14 such pillars?

Answer 1

17.584 cubic meter concrete mixture would be required to built 14 such pillars

Solution:

From given,

Each pillar has a circular base of radius 20 cm and height 10 m

Radius = 20 cm = 0.20 meter

Find volume of concrete in 1 pillar:

$\text{Volume of concrete in 1 pillar } = \pi r^2 h$

$\text{Volume of concrete in 1 pillar } = 3.14 \times 0.20^2 \times 10\\\\\text{Volume of concrete in 1 pillar } = 1.256\ m^3$

So,  concrete mixture required to built 14 such pillars is:

$\rightarrow 14 \times 1.256 = 17.584$

Thus 17.584 cubic meter concrete mixture would be required to built 14 such pillars

Answer 2

solution:

From given,

Each pillar has a circular base of radius 20cm and height 10m

Radius=20cm=0.20meter

find volume of concrete in 1 pillar:

volume of concrete in 1 pillar =$\pi$$r^{2}$h

volume of concrete in 1 pillar =3.14 x 0.$20^{2}$ x 10

volume of concrete in 1 pillar = 1.256$m^{2}$

so, concrete mixture required to build 14 such pillars is :

14 x 1.256 = 17.584

thus 17.584 cubic meter concrete mixture would be required to build 14 such pillars.
