Question

hiegt of asolid metal cone is12 cm.its radius is 9cm.
find the volume of the cone

Answer 1

Answer:

10.18sq.cm (approximately)

Step-by-step explanation:

h=12cm

r=9cm

Volume of cone= 1πr^2×h

3

=1 × 22 ×9×9×12

3 7

=22×3×9×12

7

=71.28

7

= 10.18sq.cm(approximately).

Answer 2

Step-by-step explanation:

Volume of cone-->

$v = \pi \: r {}^{2} \frac{h}{3}$

$v = \frac{22}{7} \times {9}^{2} \times \frac{12}{3}$

$v = \frac{22}{7} \times 81 \times \frac{12}{3}$

$v = 1018.2857$
