Question

find the volume of right circular conical tent whose vertical height is 8 m and the area of whose base is
$156 {m}^{2}$
please solve it because tomorrow I have my board exams.

Answer 1

Given,
Height, h = 8m
Are of base = 156m²
Now,
Area of base = πr²
156 = 22/7 x r²
r² = 156x7/22
r = √1092/22
Volume of cone = 1/3 x r²h
= (1 x 1092 x 8)/22x3
= 364 x 4 / 11
= 1456/11
= 132.36
So the volume of cone is 132.36 m³
