Question

the radious and height of the right circular cylinder are 6.5cm and 8cm find it's volume
​

Answer 1

Answer:

$Volume \: of \: right \: circular \: cylinder = 354.1 {cm}^{3}$

Step-by-step explanation:

$r = 6.5cm \: h = 8cm \\ Volume \: of \: right \: circular \: cylinder \\ = \frac{1}{3} \pi {r}^{2} h \\ = \frac{1}{3} \times \frac{22}{7} \times 6.5 \times 6.5 \times 8 \\ = \frac{1}{3} \times \frac{22}{7} \times \frac{65}{10} \times \frac{65}{10} \times 8 \\ = \frac{22 \times 13 \times 13 \times 2}{3 \times 7} \\ = \frac{7436}{21} \\ = 354.09 {cm}^{3} \\ = 354.1 {cm}^{3}$
