Question

The circus tent is in the shape of right circular cone, with base radius and height from the ground as 12 m and 16 m respectively. The area of tarpaulin required to make the tent is(Use $\Pi$ = 3.14)

• A. 656.6 $m^2$
• B. 753.6 $m^2$
• C. 824 $m^2$
• D. 882.4 $m^2$

Answer 1

The correct option is B

753.6 $m^2$

Given r=12 m , h=16 m

$l^2$ =${12}^2$+${16}^2$

Slant height l = 20 m

Curved Surface area of the tent = $\Pi$rl = 753.6 $m^2$
