Question

FIND THE VOLUME OF A RIGHT CIRCULAR CYLINDER OF RADIUS 2.8M AND HEIGHT 3.5 M​

Answer 1

To Find:-

• The radius of the cylinder is 2.8m
• The height is 3.5m

Solution:-

We know that,

$\boxed{ \boxed{ \sf{Volume = \pi {r}^{2}h \: \: cubic \: units}}}$

By putting the values,

$\longrightarrow \: V = \dfrac{22}{7} \times {2.8}^{2} \times 3.5$

By dividing 3.5 and 7 with 7

$\longrightarrow \: \dfrac{22}{7} \times 7.84 \times 3.5$

$\longrightarrow \: 22 \times 7.84 \times 0.5$

$\longrightarrow \: 86.24$

Therefore, The volume of the right circular cylinder is 86.24m³

Required Answer:-

• The volume of the right circular cylinder is 86.24m³.

Remember:-

• Volume of Cylinder = πr²h cubic units.
• Curved surface area of cylinder = 2πrh sq. units.
• Total surface area of cylinder= 2πr(h+r) sq. units.
