Answer:
Area of Closed Cylinder = Curved Surface Area of Cylinder + 2(Area of Circle)
=> \mathsf{2 \pi r h + 2(\pi r^2)}2πrh+2(πr
2
)
=> \mathsf{2 \pi r (r + h)}2πr(r+h)
\textsf{Area of Closed Cylinder =}Area of Closed Cylinder = \mathsf{2 \pi r h(r + h)}2πrh(r+h)
\underline\text{Here}
Here
,
\mathsf{\pi = \frac{22}{7}}π=
7
22
\mathsf{Radius = 7m}Radius=7m
\mathsf{Height = 3m}Height=3m
_________________________________
Substituting the values in the Formula, we get,
\mathsf{2 \times \frac{22}{7} \times 7 (7 + 3)}2×
7
22
×7(7+3)
\mathsf{= > 2 \times 22 (10)}=>2×22(10)
\mathsf{= > 44 \times 10}=>44×10
=> \boxed{\mathbf{ 440 cm^2}}
440cm
