Question

A cylindrical object has a diameter of 1.25 cm and a height of 6.48 cm. what is its volume?

Answer 1

The volume of cylinder = 7.948 cm³

Further explanation

Volume is a derivative quantity derived from the length of the principal

The unit of volume can be expressed in liters or milliliters or cubic meters

The volume of the aquarium is almost the same as the beam namely:

V = length x width x height

The volume of a cylinder can be formulated :

$\tt V=\pi.r^2.h$

r = radius

h = height

• radius

Diameter of cylinder = 1.25 cm

radius=r :

$\tt \dfrac{1.25}{2}=0.625~cm$

• volume

$\tt V=\pi\times 0.625^2\times 6.48\\\\V=\boxed{\bold{7.948~cm^3}}$
