Question

The pillars of a temple are cylindrically shaped if each pillar in height 12 m base radius 50 cm then how much concreate mixture used to build 50 such pillar

Answer 1

✬ 471 cm³ ✬

Explanation:

Given:

• Pillars of temple are cylindrically shaped.
• Height (h) of pillar is 12 m.
• Radius (r) of pillar is 50 cm.

To Find:

• How much concrete will be used to build 50 such pillars ?

Solution:

Radius of cylinder in metre = 50 $\times$ $\dfrac{1}{100}m$

➯ r = $\dfrac{1}{2}m$

As we know that

★ Volume of cylinder = ( πr²h ) ★

$\implies{\rm }$ $\dfrac{22}{7}$ $\times$ $\dfrac{1}{2}$ $\times$ $\dfrac{1}{2}$ $\times$ 12 cm³

$\implies{\rm }$ $\dfrac{264}{28}$ cm³

$\implies{\rm }$ 9.42 cm³

Volume of each pillar is 9.42 cm³.

∴ Volume of 50 pillars = 50 $\times$ 9.42 cm³ = 471 cm³

Hence, concrete used for making 50 such pillars will be 471 cm³
