<h3><u>Given </u><u>:</u><u>-</u><u> </u></h3>
• The circus tent is composed of cylinder and a cone.
• The height and diameter of the cylindrical part are 7m and 10m
• The total height of the circus tent 19m
• The cost of making the tent at a cost of 35 m² cloth.
<h3><u>Let's </u><u>Begin </u><u>:</u><u>-</u><u> </u></h3>
<u>Here</u><u>, </u><u> </u><u>we </u><u>have </u><u>,</u>
- Cylinder and cone
- The height and diameter of the cylinder are 7m and 10m
- Therefore , radius = 5 m
<u>We </u><u>know </u><u>that</u><u>, </u>
Curved Surface area of the cylinder
<u>Subsitute the required values, </u>
Thus, The area of the cylinder is 219.8m² .
<h3><u>Now</u><u>, </u></h3>
•We have to find the area of the cone.
•Here, Base of cone = diameter of the cylinder.
•The height of the cone will be
= Height of the tent - Height of cylinder
<u>We </u><u>know </u><u>that</u><u>, </u>
Area of cone
- Here, l is the slant height.
Slant height of the cone
Thus, The slant height of the cone is 13 m
<u>Subsitute </u><u>the </u><u>required </u><u>values </u><u>in </u><u>the </u><u>above </u><u>formula </u>
Thus, The area of the cone is 204.1 m² .
<h3>
<u>Therefore</u><u> </u><u>,</u></h3>
The total area of the circus tent
<h3><u>Now</u><u>, </u></h3>
- We have to find the total cost of making the tent.
- The cost for 1 m² = 35
<u>Therefore</u><u>, </u>
The total cost for making the circus tent
Hence, The total cost for making the tent is 14840 .
