Question

how much water can be stored in a glass with diametre - 6.5, Radius - 3.5, and Hieght -9cm,, Formula is V= TTr ²h​

Answer 1

Answer:-

• Radius=3.5cm=r
• Height=9cm

We know that

$\boxed{\sf Volume_{(Cylinder)}=\pi r^2h}$

$\\ \qquad\quad\sf\longmapsto Volume_{(Cylinder)}=\dfrac{22}{7}\times (3.5)^2\times 9$

$\\ \qquad\quad\sf\longmapsto Volume_{(Cylinder)}=\dfrac{22}{7}\times 12.25\times 9$

$\\ \qquad\quad\sf\longmapsto Volume_{(Cylinder)}=\dfrac{2425.5}{7}$

$\\ \qquad\quad\sf\longmapsto Volume_{(Cylinder)}=346.5cm^3$

Now

• 1 cubic cm=1litre

$\\ \qquad\quad\sf\longmapsto 346.5cm^3=346.5\ell$

Capacity of the glass tank is 346.5litres
