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

1.	FIND THE VOLUME OF A RIGHT CIRCULAR CYLINDER OF RADIUS 2.8M AND HEIGHT 3.5 M
Answer» 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, $\longrightarrow \: V = \dfrac{22}{<klux>7</klux>} \times {2.8}^{2} \times 3.5$ 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.
