Step-by-step explanation:
Answer:
1.
0.1257r^2 liters.
2.
0.314 liters.
Step-by-step explanation:
1.
Taking radius as: r.
Height given: 12 cm
→0.012 liters
Volume of Cone:
\frac{1}{3} \pi {r}^{2} h

h
1/3(22/7)r^2(0.012)
(0.088/7)r^2
0.01257r^2
Hence, the volume of the cone is 0.01257r^2.
2.
Slanting Height given: 13cm.
Using Pythagoras Theorum,
{h}^{2} = {p}^{2} + {b}^{2}h

{13}^{2} = {p}^{2} + {b}^{2}13

169 = {p }^{2} + {b}^{2}169=p

+b

169 = 144 + 25169=144+25
169 = {12}^{2} + {5}^{2}169=12
