A cylinder of manganese (length 4.00 cm, diameter = 1.00 cm) has a mass of 22.62 g. What is the density of manganese?

Gnom [1K]

Equation for density is mass/volume

Mass=22.62 g

Volume= 22/7 x 1/2^2 x 4

3.14 x 0.5 x 0.5 x 4

=3.14 cm3

Mass/ Volume

22.62/3.14

Answer:

√5 + π = 537766063.1 × $10^{-8}$

Step-by-step explanation:

given data

√5 ≈ 2.2360679775

π ≈ 3.1415926535

to find out

√5 + π

solution

√5 + π = 2.2360679775 + 3.1415926535

√5 + π = 5.3776606310

√5 + π = 5.3776606310 × $\frac{10^{-8}}{10^{-8}}$

√5 + π = 537766063.1 × $10^{-8}$
