1.	Volume of a cone is 753.60 cm3 the radius of its base is 12 cm then complete the following activity to find the height of the cone.
Answer» Volume = 753.60 cm³ Radius (r) = 12 cm Height (h) = ? Volume of cone = \(\frac{1}{3} \pi r^2 h\) 753.60 cm³ = \(\frac{1}{3} \times \frac{22}{7} \times 12 cm \times 12 cm \times h\) \(\frac{753.60 cm^3 \times 3 \times 7}{22 \times 12 \times 12 cm^2}\) = h \(\frac{15825.6 \,cm}{3168} = h\) h = 5 cm Hence, the height of the cone is 5 cm.

Volume of a cone is 753.60 cm3 the radius of its base is 12 cm then complete the following activity to find the height of the cone.

Answer»

Volume = 753.60 cm³

Radius (r) = 12 cm

Height (h) = ?

Volume of cone = \(\frac{1}{3} \pi r^2 h\)

753.60 cm³ = \(\frac{1}{3} \times \frac{22}{7} \times 12 cm \times 12 cm \times h\)

\(\frac{753.60 cm^3 \times 3 \times 7}{22 \times 12 \times 12 cm^2}\) = h

\(\frac{15825.6 \,cm}{3168} = h\)

h = 5 cm

Hence, the height of the cone is 5 cm.
