Question

The diameter of the base of a right circular cone is 12cm and volume 376.8cm find it's height

Answer 1

given-diameter of a right circular cone = 12cm
so radius = 6cm
volume of a cone = 376.8cm
to find - height of a cone.

volume of a cone =
$1 \div 3\ \pi \: r ^{2} h$
376.8 = 1/3 × 22/7 × 6 × 6 × h
376.8 ×3×7/ 22 ×6×6 = h
29.97 cm = h
height = 29.97cm
