Question

10. The circumference of base of a conical tent is 9 m
and height is 44 m. Find the volume of the air inside it​

Answer 1

Given ;

• C = 9m = 2πr

thus r = 9/2π m

• h = 44m

Thus volume of a cone ( as tent is conical);

V = 1/3 π r² h

V =

• 1/3 × π × 81/4π² × 44
• 1/3 × 81× 7/4×22 × 44
• 1/3 × 81×7/1×22 × 11
• 27×7/2
• 189/2
• 94.5 m³ of air would be present.
