Question

find the capacity of frustrum .if the radius are 1cm and 2cm and height 14cm​

Answer 1

Answer:

radius A = 1cm

radius B = 2cm

height = 14cm

Volume of the frustrum:

$volume \: = \frac{1}{3} \pi \: 14( {1 }^{2} + {2}^{2} + 1 \times 2)$

$volume = \: \frac{1}{3} \times \frac{22}{7} \times 14 (1 + 4 + 2)$

$volume \: = \frac{1}{3} \times 22 \times 2 (4)$

$volume \: = \frac{1}{3} \times 22 \times 8$

$volume \: = \: \frac{1}{3} \times 176$

$volume \: = \: 58.66$

Therefore, capacity of frustrum = 58.66cm³
