A) Rs. 52.00 (approx)
B) Rs. 39.20 (approx)
C) Rs. 35.20 (approx)
D) Rs. 23.94 (approx)
Correct Answer: D
Solution :
\[H=60\,cm\] \[R=32\,cm=\]Radius Area of the curved surface \[=\pi RL\] \[L=\sqrt{{{R}^{2}}+{{H}^{2}}}\] \[=\sqrt{{{(32)}^{2}}+{{(60)}^{2}}}\] \[\therefore \] \[L=\sqrt{1024+3600}\] \[=4624=68\,cm\] Area of the curved surface \[=\pi RL=\frac{22}{7}\times 32\times 68\] \[\therefore \] Total cost of painting \[=35\times \frac{22}{7}\times 32\times 68\times \frac{1}{1000}\] \[(100\,cm=1\,m)\] \[=5\times 22\times 32\times 68\times \frac{1}{1000}\] \[=(100\,cm=1\,m)\] \[=23.94\] approx.You need to login to perform this action.
