QUESTION
 

A conical pit of top diameter 3.5 m is 12 m deep. What is its capacity in kilolitres?

EXPLANATION
Explain TypeExplanation Content
Text

Radius of pit = r= 3.5/2 = 1.75 mheight of pit = depth of pit = 12mso, volume of pit = 1/3 λr²h= 1/3 x 22/7 x 1.75² x 12= 38.5 m³Capacity of pit = 38.5 x 1 = 38.5 kl
