Shown is a solid cylinder made from carbon. The density of carbon is 1.95g/cm
Find the mass of the cylinder.

Step-by-step explanation:

Volume of Cylinder

= Base Area * Height

= π(8cm/2)² * 15cm = 240πcm².

Hence Mass of Cylinder

= Volume * Density

= (240πcm³)(1.95g/cm³)

= 468πg or 1470g.

Radius of the cylinder=Diameter/2=8/2=4 cm

Volume of the cylinder=π(radius)²(height)

22/7×4×4×15=754 cm³(approx)

Mass of the cylinder=Density×Volume

=1.95g/cm³×754cm³

=1470 grams

Mass of the cylinder is 1470 grams

i don't have the answer rn but go to math papa. it shows the steps and the answer. hope this : )

step-by-step explanation:

the answer is 13

step-by-step explanation:

5*5=25

12*12=144

25+144=169

169^2=13
