Question

Find the slent height of a cone of radius 3.5m and height 12m.​

Answer 1

Answer:

The slant height of the cone is 12.5 cm

Step-by-step explanation:

In a cone,

l^2 = h^2 + r^2

l^2 = (12)^2 + (3.5)^2

l^2 = 144 + 12.25

l^2 = 156.25

l = 12.5 cm

Answer 2

Volume of \: a \: cone = \binom{1}{3} \pi \: {r}^{2} h

Hence, \: volume \: of \: this \: cone = \binom{1}{3} = \times \binom{22}{7} \times \binom{7}{2} \times 12 = 154cm
