Question

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

Answer 1

Answer:

Hy friend, thanx for asking the question...

Here's ur ans....

9025

5×5×19×19

We hv a pair of 5 and a pair of 19

Take one 5 and one 19 from it,

That is,

5×19

95

\sqrt{9025 } = \: 95

9025

=95

Hope it helped u...

Step-by-step explanation:

In mathematics, the logarithm is the inverse function to exponentiation. That means the logarithm of a given number x is the exponent to which another fixed number, the base b, must be raised, to produce that number x.

Answer 2

Answer:Answer

Considering it to a solid cylinder, for amount of concrete making are cylinder = volume of cylinder

∴ Amount of concrete mixture required to fild 14 such pillars =14× volume of a cylinder−−−−−(1)

If Volume of cylinder where =πr

2

h

x=radius

h=height

Volume =π×x

2

×h

=π×20×20×10 cm

3

=4000π cm

3

=4000×3.142 cm

3

=12568 cm

3

Substituting it in equation (1)

=14×12568

=150816 cm

3

∴ Amount of concrete mixture required to build 14 such pillars =150816 cm
