Question

inner radius is1.5 m and outer radius is 2m and height is2m find the volume of the ring??? please argent​

Answer 1

Given

• Inner radius = 1.5m
• Outer radius = 2m
• Height = 2m

⠀

To find

• Volume of the ring.

⠀

Solution

• As it is a ring, we have to use the given Formula to calculate the volume.

⠀

$\star{\boxed{\boxed{\bf{Volume_{(Ring)} = \pi h (R^2 - r^2)}}}}$

⠀

Here,

• R = outer radius
• r = inner radius

⠀

$\: \: \: \: \: \: \: \: \: \:\underline{\sf{\red{Putting\: the\: values}}}$

⠀

$\tt:\implies\: \: \: \: \: \: \: \: {Volume = \dfrac{22}{7} \times 2 \bigg\lgroup (2)^2 - (1.5)^2 \bigg\rgroup}$

⠀

$\tt:\implies\: \: \: \: \: \: \: \: {Volume = \dfrac{44}{7} \times \bigg\lgroup 4 - 2.25 \bigg\rgroup}$

⠀

$\tt:\implies\: \: \: \: \: \: \: \: {Volume = \dfrac{44}{7} \times 1.75}$

⠀

$\tt:\implies\: \: \: \: \: \: \: \: {Volume = 44 \times 0.25}$

⠀

$\mathfrak:\implies\: \: \: \: \: \: \: \: {\underline{\boxed{\purple{Volume = 11\: m^3}}}}$

⠀

Hence,

• Volume of the ring is 11m³.
