Question

the height of cylinder is 7cm and its mass is 264g if it's radius is 2 cm then calculate the density of the cylinder(take π=22/7)​

Answer 1

Answer:

7 × 264 × 2 × 22/7 will be your answer

Explanation:

IT'S 11616

Answer 2

Answer

Height= 7cm

Mass= 264g

Radius= 2cm

$volume =\pi {r}^{2}h \\ = \frac{22}{7} \times 2 \times 2 \times 7 \\ =( 22 \times 2 \times 2) {cm}^{3} \\ = 88 {cm}^{3}$

Now,

$density = \frac{g}{ {cm}^{3} } \\ = \frac{264}{88} g {cm}^{ - 3} \\ = 3g {cm}^{ - 3} (answer)$
